<h2>About Yandex.Metrica</h2>
|
||||
<p>Yandex.Metrica (https://metrica.yandex.com/) is a service for web analytics.</p>
|
||||
<p>Largest in Russia, second largest in the world (just after Google Analytics).</p>
|

<p><img src="pictures/metrika_market_share.png"/></p>
|
||||
<p>We are processing about ~25 billions of events (page views, conversions, etc).</p>
|
||||
<p>We must generate and show reports in realtime.</p>

<h2>How to store data?</h2>
|
||||
<p>Big data processing is not a problem.</p>
|
||||
<p>The challenge is how to store data in that way to allow both:</p>
|
||||
<p>- efficient ingestion of click stream in realtime;</p>
|
||||
<p>- efficient generation of reports;</p>
|
||||
<p> </p>
|
||||
<p>Let review our historical solutions first...</p>
|
||||
</section>
|
||||
|
||||
<section class="slide">
|
||||
<h2>MySQL (MyISAM) 2008-2011</h2>
|
||||
<p>We have had about 50 predefined report types.</p>
|
||||
<p>We create a table for each of them.</p>
|
||||
<p>Each table has primary key in form of:</p>
|
||||
<p> site_id, date, <i>key</i> -> aggregated statistics.</p>
|
||||
<p>The data was inserted in mini-batches of aggregated deltas,<br/>using ON DUPLICATE KEY UPDATE.</p>
|
||||
<p> </p>
|
||||
<p>... but this just don't work.</p>
|
||||
</section>
|
||||
|
||||
<section class="slide">
|
||||
<h2>Data locality on disk (artistic view)</h2>
|
||||
<p>The main concern is <b>data locality</b>.</p>
|
||||
<img src="pictures/data_locality.png" style="width:100%"/>
|
||||
</section>
|
||||
|
||||
<section class="slide">
|
||||
<h2>MySQL (MyISAM) 2008-2011</h2>
|
||||
<p>We use HDD (rotational drives).<br/>We cannot afford petabytes of SSDs.</p>
|
||||
<p>Each seek is ~12 ms of latency,<br/> usually no more than 1000 random reads/second in RAID array.</p>
|
||||
|
||||
<p>Time to read data from disk array is dependent on:<br />- number of seeks;<br />- total amount of data;</p>
|
||||
|
||||
<p>Example: read 100 000 rows, randomly scattered on disk:<br />- at least 100 seconds in worst case.<br />User won't wait hundred seconds for the report.</p>
|
||||
|
||||
<p>The only way to read data from disk array in appropriate amount of time is to minimize number of seek by maintaining data locality.</p>
|
||||
</section>
|
||||
|
||||
<section class="slide">
|
||||
<h2>MySQL (MyISAM) 2008-2011</h2>
|
||||
<p>Fundamental problem:</p>
|
||||
|
||||
<p>Data is <b>inserted</b> almost in time order:
|
||||
<br />- each second we have new portion data for this second;
|
||||
<br />- but data for different web sites are comes in random order in a stream;</p>
|
||||
|
||||
<p>Data is <b>selected</b> by ranges for specified web site and date period:
|
||||
<br />- in ranges of completely different order;</p>
|
||||
</section>
|
||||
|
||||
<section class="slide">
|
||||
<h2>MySQL (MyISAM) 2008-2011</h2>
|
||||
<p>MyISAM stores data in MYD and MYI files.<br/>MYD contains data almost in order of insertion.<br/>MYI contains B-tree index that maps a key to offset in MYD file.</p>
|
||||
<p>Insertion of data is almost fine.<br />But selecting of data by range of primary key was non-practical.</p>
|
||||
<p>Nevertheless, we made it work by:</p>
|
||||
<p>
|
||||
- tricky partitioning;<br/>
|
||||
- organizing data in few generations with different partitioning scheme;<br/>
|
||||
- moving data between tables by scheduled scripts;<br/>
|
||||
- report generation becomes ugly UNION ALL queries.</p>
|
||||
</section>
|
||||
|
||||
<section class="slide">
|
||||
<h2>MySQL (MyISAM) 2008-2011</h2>
|
||||
<p>As of 2011 we was storing about 580 billion rows in MyISAM tables.</p>
|
||||
<p>We were not satisfied by performance and maintenance cost:<br/>
|
||||
Example: page title report loading time, 90% quantile was more than 10 seconds.</p>
|
||||
<p>... After all, everything was converted and deleted.</p>
|
||||
</section>
|
||||
|
||||
<section class="slide">
|
||||
<h2>Metrage, 2010-2015</h2>
|
||||
<p>(Specialized data structure, developed specially for aggregation of data and report generation).</p>
|
||||
<p>To maintain data locality, we need<br/>to constantly reordering data by primary key.</p>
|
||||
<p>We cannot maintain desired order at INSERT time, nor on SELECT time;<br/>we must do it in background.</p>
|
||||
<p><i>Obviously</i>: we need an LSM-tree!</p>

</section>

<section class="slide">
|

<h2>Metrage, 2010-2015</h2>
|
||||
<p>Metrage: <b>Metr</b>ica + <b>Ag</b>gregated statistics.</p>
|
||||
<p>We have created custom data structure for that purpose.</p>
|
||||
<p>In 2010, there was no LevelDB.<br />We just got some insights from article about TokuDB.</p>
|
||||
<p>Metrage is designed for the purpose of realtime data aggregation:<br/>
|
||||
- row in Metrage table is custom C++ struct with <i>update</i> and <i>merge</i> methods.</p>
|
||||
<p>Example: a row in Metrage table could contain a HyperLogLog.</p>
|
||||
<p>Data in Metrage is aggregated:<br/>- on insertion, in batches;<br/>- during background compaction;<br/>- on the fly, during report generation.</p>

|

|
||||
<section class="slide">
|
||||
<h2>Metrage, 2010-2015</h2>
|
||||
<p>Everything was working fine.<br/>The problem of data locality was solved.<br/>Reports was loading quickly.</p>
|
||||
<p>As of 2015 we stored 3.37 trillion rows in Metrage<br/>and used 39 * 2 servers for this.</p>
|
||||
<p>But we have had just ~50 pre-defined reports.</p>
|
||||
<p>No customization and drill down was possible.</p>
|
||||
<p>The user wants to slice and dice every report by every dimension!</p>
|
||||
<p> </p>
|
||||
<p>... and we have developed just another custom data structure.</p>

||||
</section>
|

<section class="slide">
|
||||
<h2>The report builder, 2010</h2>
|
||||
<p>We had quickly made a prototype of so-called "report builder".</p>
|
||||
<p>This was 2010 year. It was just simple specialized column-oriented data structure.</p>
|
||||
<p>It worked fine and we got understanding, what the right direction to go.</p>
|
||||
<p>We need good column-oriented DBMS.</p>
|
||||
</section>
|
||||
|
||||
<section class="slide">
|
||||
<h2>Why column-oriented?</h2>
|
||||
<p>This is how "traditional" row-oriented databases work:</p>

</section>
|

|

<section class="slide">
|
||||
<h2>Why column-oriented?</h2>
|
||||
<p>Hypothesis:</p>
|
||||
<p>If we have good enough column-oriented DBMS,<br/>we could store all our data in non-aggregated form<br/>(raw pageviews and sessions) and generate all the reports on the fly,<br />to allow infinite customization.</p>
|
||||
<p>To check this hypothesis, we started to evaluate existing solutions.</p>
|
||||
<p>MonetDB, InfiniDB, Infobright and so on...</p>
|
||||
<p>No appropriate solutions were exist in 2010.</p>

<section class="slide">
|
||||
<h2>ClickHouse</h2>
|
||||
<p>As an experimental project, we started to develop<br />our own column-oriented DBMS: ClickHouse.</p>
|
||||
<p>In 2012 it was in production state.</p>
|
||||
<p>In 2014 we re-lauched Yandex.Metrica as Metrica 2.</p>
|
||||
<p>All data is stored in ClickHouse and in non-aggregated form<br />and every report is generated on the fly.</p>
|
||||
<p>In Metrika 2 the user could create it's own report with<br />
|
||||
- custom dimensions, metrics, filters, user-centric segmentation...<br/>
|
||||
- and to dig through data to the detail of individual visitors.</p>
|
||||
</section>
|
||||
|
||||
<section class="slide">
|
||||
<h2>ClickHouse</h2>
|
||||
<p>The main target for ClickHouse is query execution speed.</p>
|
||||
<p>In Yandex.Metrika, users could analyze data for their web sites of any volume.</p>
|
||||
<p>Biggest classifieds and e-commerce sites with hundreds millions PV/day are using Yandex.Metrika (e.g. ru.aliexpress.com).</p>
|
||||
<p>In contrast to GA*, in Yandex.Metrika, you could get data reports for large web sites without sampling.</p>
|
||||
<p>As data is processed on the fly, ClickHouse must be able to crunch all that pageviews in sub second time.</p>
|
||||
<p style="font-size:60%; margin-top:2em">* in Google Analytics you could get reports without sampling only in "premium" version.</p>

<h2>ClickHouse vs. PrestoDB</h2>
|

<p>Ömer Osman Koçak:<br /><br />
|

«When we evaluated ClickHouse the results were great compared to Prestodb. Even though the columnar storage optimizations for ORC and Clickhouse is quite similar, Clickhouse uses CPU and Memory resources more efficiently (Presto also uses vectorized execution but cannot take advantage of hardware level optimizations such as SIMD instruction sets because it's written in Java so that's fair) so we also wanted to add support for Clickhouse for our open-source analytics platform Rakam (https://github.com/rakam-io/rakam)»</p>

<p>MergeTree, locality of data on disk<br/>— fast range queries.</p>

<p>Itai Shirav:<br /><br />«I haven't made a rigorous comparison, but I did convert a time-series table with 9 million rows from Postgres to ClickHouse.</p>
|

<p>Under ClickHouse queries run about 100 times faster, and the table takes 20 times less disk space. Which is pretty amazing if you ask me».</p>

# Ribbon theme for Shower [](https://travis-ci.org/shower/ribbon)
|
||||
|
||||
|
||||
|
||||
Default theme for the [Shower](https://github.com/shower/shower/) presentation engine. Doesn’t include engine itself. [See it in action](http://shwr.me/shower/themes/ribbon/). Follow [@shower_me](https://twitter.com/shower_me) for support and updates, [file an issue](https://github.com/shower/shower/issues/new) if you have any.
|
||||
|
||||
## Usage
|
||||
|
||||
Get the Shower template where Ribbon is already included. Download the [template archive](http://shwr.me/shower.zip) or install the package:
|
||||
|
||||
npm install shower
|
||||
|
||||
If you want to install Ribbon separately you can download the [theme archive](http://shwr.me/ribbon.zip) or install the package:
|
||||
|
||||
npm install shower-ribbon
|
||||
|
||||
## Features
|
||||
|
||||
All theme’s features are demonstrated in the [index.html](index.html) file. Use it as a reference while building your presentation. See more detailed [features overview](https://github.com/shower/shower/blob/master/docs/features-en.md).
|
||||
|
||||
## Ratios
|
||||
|
||||
Ribbon theme supports two slide ratios: wide 16×10 (default) and taller 4×3. To change the slide’s ratio include one of the pre-built `screen-16x10.css` or `screen-4x3.css` files in the `<head>` of your presentation.
|
||||
|
||||
## PDF
|
||||
|
||||
Ribbon could be exported to PDF by printing it from the list mode in Chrome or Opera browsers. See [printing documentation](https://github.com/shower/shower/blob/master/docs/printing-en.md) for more options.
|
||||
|
||||
## Development
|
||||
|
||||
If you want to adjust theme for your needs:
|
||||
|
||||
1. Fork this repository and clone it to your local machine.
|
||||
2. Install dependencies: `npm install`.
|
||||
3. Start a local server with watcher: `npm run dev` or just `gulp` if you have it installed globally.
|
||||
4. Edit your files and see changes in the opened browser.
|
||||
|
||||
To take part in Ribbon development please read [contributing guidelines](CONTRIBUTING.md) first and [file an issue](https://github.com/shower/shower/issues/new) before sending any pull request.

## Quick Start
|
||||
|
||||
1. Download and unzip [template archive](http://shwr.me/shower.zip)
|
||||
2. Open `index.html` and start creating your presentation
|
||||
|
||||
## Advanced
|
||||
|
||||
1. [Fork](https://github.com/shower/shower/fork) this repository
|
||||
2. Go to fork setting and rename it: `shower` → `my-slides`
|
||||
2. Clone it to your computer: `git clone git@github.com:username/my-slides.git`
|
||||

<p>Достоинства:</p>

<p>− пусть N — общее число данных, а M — количество ключей;

<h2>1. Тривиальный способ</h2>
|
||||
|
||||
<p>Разные потоки читают разные данные по мере возможности.
|
||||
Агрегируют независимо в свои локальные хэш-таблицы.
|
||||
Когда все данные прочитаны, мержим все хэш-таблицы в одну.
|
||||
Например, идём по всем локальным хэш-таблицам кроме первой
|
||||
и перекладываем всё в первую.
|
||||
|
||||
Фаза чтения данных и предварительной агрегации распараллеливается.
|
||||
Фаза мержа выполняется последовательно.
|
||||
|
||||
Пусть N — общее число данных, а M — количество ключей.
|
||||
O(M) работы выполняется последовательно
|
||||
и при большом M (кардинальность GROUP BY)
|
||||
работа плохо распараллеливается.
|
||||
|
||||
Достоинства: тривиально.
|
||||
|
||||
Недостатки: не масштабируется при большой кардинальности.</p>
|
||||
</section>
|
||||
|
||||
|
||||
<section class="slide">
|
||||
<h2>2. Partitioning способ</h2>
|
||||
|
||||
<p>Для каждого блока данных, выполняем агрегацию в две стадии:
|
||||
|
||||
Стадия 1.
|
||||
Разные потоки будут обрабатывать разные куски блока, какие успеют.
|
||||
В каждом потоке, с помощью отдельной хэш-функции,
|
||||
хэшируем ключ в номер потока и запоминаем его.
|
||||
|
||||
hash: key -> bucket_num
|
||||
|
||||
Стадия 2.
|
||||
Каждый поток идёт по всему блоку данных
|
||||
и берёт для агрегации только строки с нуждым номером корзины.
|
||||
|
||||
Модификация: можно всё в одну стадию — тогда каждый поток
|
||||
будет вычислять хэш-функцию от всех строк заново:
|
||||
подходит, если это дёшево.
|
||||
</section>
|
||||
|
||||
<section class="slide">
|
||||
<p>
|
||||
Достоинства:
|
||||
+ хорошо масштабируется при большой кардинальности
|
||||
и равномерном распределении ключей;
|
||||
+ идейная простота.
|
||||
|
||||
Недостатки:
|
||||
− если объём данных распределён неравномерно по ключам,
|
||||
то стадия 2 плохо масштабируется.
|
||||
Это типичный случай.
|
||||
Почти всегда объём данных по ключам распределён по power law.
|
||||
|
||||
Ещё недостатки:
|
||||
− если размер блока маленький, то получается слишком
|
||||
мелко-гранулированная многопоточность:
|
||||
большой оверхед на синхронизацию;
|
||||
− если размер блока большой, то плохая кэш-локальность;
|
||||
− на второй стадии, часть memory bandwidth умножается на число потоков;
|
||||
− нужно вычислять ещё одну хэш-функцию,
|
||||
она должна быть независима от той, что в хэш-таблице;</p>

<h2>3. Параллельный мерж хэш-таблиц</h2>
|

|
||||
<p>Отресайзим полученные в разных потоках хэш-таблицы к одному размеру.
|
||||
Разобъём их неявно на разные подмножества ключей.
|
||||
В разных потоках будем мержить соответствующие
|
||||
подмножества ключей хэш-таблиц.

||||

<h2>4. Ordered мерж хэш-таблиц</h2>
|
||||
|
||||
<p>Для open addressing linear probing хэш-таблиц, или для chaining хэш-таблиц,
|
||||
данные в хэш-таблице расположены почти упорядоченно
|
||||
по остатку от деления хэш-функции на размер хэш-таблицы
|
||||
— с точностью до цепочек разрешения коллизий.
|
||||
|
||||
Отресайзим полученные в разных потоках хэш-таблицы к одному размеру.
|
||||
Сделаем ordered iterator, который будет
|
||||
перебирать данные в хэш-таблице в фиксированном порядке.
|
||||
|
||||
Объём работы на итерирование:
|
||||
количество цепочек разрешения коллизий * средний квадрат длин цепочек.
|
||||
|
||||
Сделаем merging iterator, который с помощью heap (priority queue)
|
||||
будет перебирать все хэш-таблицы разом.
|
||||
</section>
|
||||
|
||||
<section class="slide">
|
||||
<p>Достоинства:
|
||||
|
||||
+ не нужно никуда перекладывать элементы: мерж делается inplace.
|
||||
|
||||
+ бонус: подходит для внешней памяти.
|
||||
|
||||
|
||||
Недостатки:
|
||||
|
||||
− отвратительно сложный код;
|
||||
|
||||
− для open addressing linear probing хэш-таблиц,
|
||||
средний квадрат длин цепочек разрешения коллизий слишком большой;
|
||||
|
||||
− priority queue тормозит;
|
||||
|
||||
− стадия мержа не распараллеливается*
|
||||
|
||||
|
||||
* — можно совместить с предыдущим способом.</p>

<h2 style="font-size: 40px;">5. Robin Hood ordered мерж хэш-таблиц</h2>
|
||||
|
||||
<p>Если использовать Robin Hood хэш-таблицу, то данные
|
||||
(за исключением O(1) граничных цепочек разрешения коллизий)
|
||||
будут полностью упорядочены
|
||||
по остатку от деления хэш-функции на размер хэш-таблицы.
|
||||
|
||||
Достоинства:
|
||||
+ вроде бы красивый алгоритм.
|
||||
+ бонус: подходит для внешней памяти.
|
||||
|
||||
Недостатки:
|
||||
− вынуждает использовать robin-hood probing;
|

− priority queue тормозит;

− стадия мержа не распараллеливается*</p>

||||
− в типичном случае данные распределены сильно неравномерно,
|
||||
и потоки будут конкурировать на одной горячей ячейке:
|
||||
false sharing, тормоза.
|
||||
|
||||
− сложный код, много инструкций, всё тормозит;
|
||||
|
||||
− я вообще недолюбливаю lock-free алгоритмы.</p>

<h2 style="font-size: 35px;">10. Shared хэш-таблица + thread local хэш-таблицы</h2>
|
||||
|
||||
<p>Пытаемся положить в shared хэш-таблицу путём блокирования ячейки;
|
||||
если ячейка уже заблокирована — кладём к локальную хэш-таблицу.
|
||||
|
||||
Тогда горячие ключи попадут в локальные хэш-таблицы.
|
||||
Локальные хэш-таблицы будут маленькими.
|
||||
В конце мержим все локальные хэш-таблицы в глобальную.
|
||||
|
||||
Дополнения: можно сначала смотреть
|
||||
на наличие ключа в локальной хэш-таблице.
|
||||
|
||||
Достоинства:
|
||||
+ отлично масштабируется;
|
||||
+ сравнительно простая реализация.
|
||||
|
||||
Недостатки:
|
||||
− много лукапов, много инструкций — в целом довольно медленно.
|
||||
|
||||
Даже не смотря на то, что thread local хэш-таблица
|
||||
зачастую ещё и cache local.</p>

<h2>11. Two-level хэш-таблица</h2>
|
||||
|
||||
<p>На первой стадии, в каждом потоке независимо
|
||||
кладём данные в свои num_buckets = 256 хэш-таблиц,
|
||||
хранящих разные ключи.
|
||||
|
||||
В какую из них класть (номер корзины)
|
||||
определяется другой хэш-функцией,
|
||||
либо отдельным байтом хэш-функции.
|
||||
|
||||
Имеем num_threads * num_buckets хэш-таблиц.
|
||||
|
||||
На второй стадии мержим состояния
|
||||
num_threads * num_buckets хэш-таблиц
|
||||
в одни num_buckets хэш-таблиц,
|
||||
распараллеливая мерж по bucket-ам.
|
||||
</section>
|
||||
|
||||
<section class="slide">
|
||||
<p>
|
||||
Достоинства:
|
||||
|
||||
+ отлично масштабируется;
|
||||
+ простота реализации;
|
||||
|
||||
+ бонус: ресайзы хэш-таблиц амортизируются;
|
||||
|
||||
+ бонус: нахаляву получаем в результате partitioning,
|
||||
который полезен для других стадий конвейера.
|
||||
|
||||
+ бонус: подходит для внешней памяти.
|
||||
|
||||
Недостатки:
|
||||
|
||||
− при большой кардинальности, во время мержа
|
||||
делается до такого же объёма работ как на первой стадии;
|
||||
|
||||
− при маленькой кардинальности,
|
||||
слишком много отдельных хэш-таблиц;
|
||||
|
||||
− при маленькой кардинальности,
|
||||
работает несколько медленнее тривиального способа;</p>

|

<p>Используем тривиальный способ.
|
||||
|
||||
Когда разных ключей много, конвертируем в two-level.</p>

|

|

<p>На разных машинах расположены части данных,

|
||||
|
||||
Отличия от shared memory:
|
||||
|
||||
— почти отсутствует возможность work stealing;
|

— нужно явно передавать данные по сети.</p>

<h2>1. Тривиальный способ</h2>
|

<p>Передаём промежуточные результаты на сервер-инициатор запроса.
|

Последовательно кладём всё в одну хэш-таблицу.
|

|
||||
Достоинства:
|
||||
|

+ тривиально;
|

+ хорошо масштабируется при маленькой кардинальности.
|

|

Недостатки:

|

|

Достоинства:
|

+ тратится O(1) оперативки;
|

|

Недостатки:
|
||||
− при большой кардинальности не масштабируется;
|
||||
− мерж сортированных потоков (heap) — это медленная операция;
|

− требуется либо сортировать результаты на удалённых серверах,

<h2>3. Partitioned merge</h2>

разбитыми на отдельные согласованные корзины-партиции,
|

в заданном порядке корзин.
|
||||
|
||||
Мержим по одной или по несколько корзин одновременно.
|
||||
|
||||
Достоинства:
|
||||
+ тратится до в num_buckets раз меньше оперативки, чем размер результата;
|
||||
+ можно легко распараллелить, мержа сразу несколько корзин
|
||||
— отлично масштабируется по ядрам.
|
||||
|
||||
Недостатки:
|
||||
− мерж делается на одном сервере — инициаторе запроса
|
||||
— эта стадия не масштабируется по серверам.</p>

<h2>4. Reshuffle + partitioned merge</h2>

<p>На удалённых серверах получаем промежуточные результаты,

разбитые на согласованные партиции.
|
||||
|
||||
Затем передаём партиции между серверами так,
|
||||
чтобы на разных серверах были разные партиции,
|

а данные одной партиции оказались на одном сервере.
|
||||
|
||||
Мержим на всех серверах параллельно, да ещё и используя многие ядра.
|
||||
|
||||
Достоинства:
|
||||
+ прекрасно масштабируется;
|
||||
+ при INSERT SELECT, результат можно
|
||||
вовсе не передавать на сервер-инициатор,
|
||||
а сразу сохранить в распределённую таблицу на кластере.
|
||||
|

Недостатки:

− сложная координация серверов;</p>

||||
Ribbon theme supports two slide ratios: wide 16×10 (default) and taller 4×3. To change the slide’s ratio include one of the pre-built `screen-16x10.css` or `screen-4x3.css` files in the `<head>` of your presentation.
|
||||
|
||||
## PDF
|
||||
|
||||
Ribbon could be exported to PDF by printing it from the list mode in Chrome or Opera browsers. See [printing documentation](https://github.com/shower/shower/blob/master/docs/printing-en.md) for more options.

# Ribbon theme for Shower [](https://travis-ci.org/shower/ribbon)
|
||||
|
||||
|
||||
|
||||
Default theme for the [Shower](https://github.com/shower/shower/) presentation engine. Doesn’t include engine itself. [See it in action](http://shwr.me/shower/themes/ribbon/). Follow [@shower_me](https://twitter.com/shower_me) for support and updates, [file an issue](https://github.com/shower/shower/issues/new) if you have any.
|
||||
|
||||
## Usage
|
||||
|
||||
Get the Shower template where Ribbon is already included. Download the [template archive](http://shwr.me/shower.zip) or install the package:
|
||||
|
||||
npm install shower
|
||||
|
||||
If you want to install Ribbon separately you can download the [theme archive](http://shwr.me/ribbon.zip) or install the package:
|
||||
|
||||
npm install shower-ribbon
|
||||
|
||||
## Features
|
||||
|
||||
All theme’s features are demonstrated in the [index.html](index.html) file. Use it as a reference while building your presentation. See more detailed [features overview](https://github.com/shower/shower/blob/master/docs/features-en.md).
|
||||
|
||||
## Ratios
|
||||
|
||||
Ribbon theme supports two slide ratios: wide 16×10 (default) and taller 4×3. To change the slide’s ratio include one of the pre-built `screen-16x10.css` or `screen-4x3.css` files in the `<head>` of your presentation.
|
||||
|
||||
## PDF
|
||||
|
||||
Ribbon could be exported to PDF by printing it from the list mode in Chrome or Opera browsers. See [printing documentation](https://github.com/shower/shower/blob/master/docs/printing-en.md) for more options.
|
||||
|
||||
## Development
|
||||
|
||||
If you want to adjust theme for your needs:
|
||||
|
||||
1. Fork this repository and clone it to your local machine.
|
||||
2. Install dependencies: `npm install`.
|
||||
3. Start a local server with watcher: `npm run dev` or just `gulp` if you have it installed globally.
|
||||
4. Edit your files and see changes in the opened browser.
|
||||
|
||||
To take part in Ribbon development please read [contributing guidelines](CONTRIBUTING.md) first and [file an issue](https://github.com/shower/shower/issues/new) before sending any pull request.

<h2>ClickHouse в Яндексе</h2>
|
||||
<p>Нам удалось сделать систему сравнительно удобной.</p>
|
||||
<p>С самого начала мы имели подробную документацию.</p>
|
||||
<p>В течение пары лет ClickHouse распространился по другим отделам Яндекса.</p>
|
||||
<p>Почта, Маркет, Директ, Вебмастер, AdFox, Инфраструктура, Бизнес аналитика...</p>
|
||||
<p>Есть случаи, когда аналитики самостоятельно устанавливали ClickHouse на виртуальные машины и успешно использовали без каких-либо вопросов.</p>
|
||||
</section>
|
||||
<section class="slide">
|
||||
<h2>Open-source</h2>
|
||||
<p>Потом мы решили — ClickHouse слишком хорошая система, чтобы нам одним на нём сидеть.</p>
|
||||
<p>Чтобы было веселее, надо подсадить на ClickHouse людей снаружи, пусть радуются. Решили сделать open-source.</p>
|
||||
</section>
|
||||
<section class="slide">
|
||||
<h2>Open-source</h2>
|
||||
<p>Лицензия Apache 2.0 — минимум ограничений.</p>
|
||||
<p>Цель — максимальное распространение продукта.</p>
|
||||
<p>Мы хотим, чтобы продуктом Яндекса пользовались по всему миру.</p>

<h2>Когда надо использовать ClickHouse</h2>
|
||||
<p>Хорошо структурированные, очищенные, неизменяемые события.</p>
|
||||
<p> </p>
|
||||
<p>Click stream. Веб-аналитика. Рекламные сети. RTB. E-commerce.</p>
|
||||
<p>Аналитика онлайн игр. Данные сенсоров и мониторингов. Телеком данные.</p>
|
||||
<p>Финансовые транзакции. Биржевая аналитика.</p>

<section class="slide">
|

<h2 style="font-size: 40px;">Когда <span style="color:red;">не надо</span> использовать ClickHouse</h2>
|
||||
<p><span style="font-size: 30px;color: #888;">OLTP</span><br/>В ClickHouse нет UPDATE и полноценных транзакций.</p>
|
||||
<p><span style="font-size: 30px;color: #888;">Key-Value</span><br/>Если нужны частые запросы на обновление по ключу, используйте другое решение.</p>
|
||||
<p><span style="font-size: 30px;color: #888;">Blob-store, document oriented</span><br/>ClickHouse предназначен для большого количества мелко-гранулированных данных.</p>
|
||||
<p><span style="font-size: 30px;color: #888;">Излишне нормализованные данные</span><br/>Лучше сделать широкую таблицу фактов.</p>

<section class="slide">
|
||||
<h2>Почему ClickHouse такой быстрый?</h2>
|
||||
<p> </p>
|

<h2>Почему ClickHouse такой быстрый?</h2>
|
||||
<p><b>Алгоритмическая оптимизация.</b></p>
|
||||
<p>MergeTree, локальность расположения данных на диске<br/>— быстрые диапазонные запросы.</p>
|
||||
<p>Пример: функция uniqCombined состоит из комбинации трёх различных структур данных, подходящих под разные диапазоны кардинальностей.</p>
|
||||
<p><b>Низкоуровневая оптимизация.</b></p>
|
||||
<p>Пример: vectorized query execution.</p>
|
||||
<p><b>Специализация и внимание к деталям.</b></p>
|
||||
<p>Пример: у нас есть 17 разных алгоритмов выполнения GROUP BY. Для вашего запроса выбирается лучший.</p>

<h2>ClickHouse vs. PrestoDB</h2>
|
||||
<p>Ömer Osman Koçak:<br /><br />
|
||||
«When we evaluated ClickHouse the results were great compared to Prestodb. Even though the columnar storage optimizations for ORC and Clickhouse is quite similar, Clickhouse uses CPU and Memory resources more efficiently (Presto also uses vectorized execution but cannot take advantage of hardware level optimizations such as SIMD instruction sets because it's written in Java so that's fair) so we also wanted to add support for Clickhouse for our open-source analytics platform Rakam (https://github.com/rakam-io/rakam)»</p>

<h2>ClickHouse vs. Google BigQuery</h2>
|

<p>«ClickHouse показывает сравнимую скорость на <u>таком запросе</u> за 30 дней и в 8 раз быстрее (!) на <u>таком запросе</u>. В планах есть протестировать и другие запросы, еще не добрались.<br/><br/>Скорость выполнения запросов стабильна. В Google BigQuery в период пиковых нагрузок, например в 4:00 p.m. PDT или в начале месяца, время выполнения запросов может заметно увеличиваться».</p>

<h2>ClickHouse vs. Druid</h2>

# Ribbon theme for Shower [](https://travis-ci.org/shower/ribbon)
|
||||
|
||||
|
||||
|
||||
Default theme for the [Shower](https://github.com/shower/shower/) presentation engine. Doesn’t include engine itself. [See it in action](http://shwr.me/shower/themes/ribbon/). Follow [@shower_me](https://twitter.com/shower_me) for support and updates, [file an issue](https://github.com/shower/shower/issues/new) if you have any.
|
||||
|
||||
## Usage
|
||||
|
||||
Get the Shower template where Ribbon is already included. Download the [template archive](http://shwr.me/shower.zip) or install the package:
|
||||
|
||||
npm install shower
|
||||
|
||||
If you want to install Ribbon separately you can download the [theme archive](http://shwr.me/ribbon.zip) or install the package:
|
||||
|
||||
npm install shower-ribbon

|
||||
|
||||
## Ratios
|
||||
|
||||
Ribbon theme supports two slide ratios: wide 16×10 (default) and taller 4×3. To change the slide’s ratio include one of the pre-built `screen-16x10.css` or `screen-4x3.css` files in the `<head>` of your presentation.
|
||||
|
||||
## PDF
|
||||
|
||||
Ribbon could be exported to PDF by printing it from the list mode in Chrome or Opera browsers. See [printing documentation](https://github.com/shower/shower/blob/master/docs/printing-en.md) for more options.
|
||||
|
||||
## Development
|
||||
|
||||
If you want to adjust theme for your needs:
|
||||
|
||||
1. Fork this repository and clone it to your local machine.
|
||||
2. Install dependencies: `npm install`.
|
||||
3. Start a local server with watcher: `npm run dev` or just `gulp` if you have it installed globally.
|
||||
4. Edit your files and see changes in the opened browser.
|
||||

<h2>Обо мне</h2>
|
||||
<p>Алексей, разработчик ClickHouse.</p>
|
||||
<p>С 2008 занимался движком обработки данных в Яндекс.Метрике.</p>
|
||||
</section>
|
||||
<section class="slide">
|
||||
<h2>История</h2>
|
||||
<p>Яндекс.Метрика — сервис веб-аналитики.</p>
|
||||
<p>В России первый, в мире — второй.</p>
|
||||
<p><img src="pictures/metrika_market_share.png"/></p>
|
||||
<p>Ежедневно приходит ~25 млрд. событий.</p>
|
||||
<p>Надо показывать отчёты в реальном времени.</p>
|
||||
</section>
|
||||
<section class="slide">
|
||||
<h2>Старая Метрика (2008–2014)</h2>
|
||||
<p>Всё отлично работало. Пользователь мог получить примерно 50 разных отчётов.</p>
|
||||
<p>Но есть проблема. Нам хочется большего. Чтобы каждый отчёт был сколь угодно кастомизируемым.</p>
|
||||
</section>
|
||||
<section class="slide">
|
||||
<h2>Конструктор отчётов</h2>
|
||||
<p>Быстро сделали прототип и на его основе реализовали "Конструктор отчётов".</p>
|
||||
<p>Это 2010 год.</p>
|
||||
<p>Стало понятно, куда двигаться дальше. </p>
|
||||
<p>Нам нужна хорошая column-oriented DBMS.</p>

|

<h2>ClickHouse в Яндексе</h2>
|
||||
<p>Нам удалось сделать систему сравнительно удобной.</p>
|
||||
<p>С самого начала мы имели подробную документацию.</p>
|
||||
<p>В течение пары лет ClickHouse распространился по другим отделам Яндекса.</p>
|
||||
<p>Почта, Маркет, Директ, Вебмастер, AdFox, Инфраструктура, Бизнес аналитика...</p>
|
||||
<p>Есть случаи, когда аналитики самостоятельно устанавливали ClickHouse на виртуальные машины и успешно использовали без каких-либо вопросов.</p>
|
||||
</section>
|
||||
<section class="slide">
|
||||
<h2>Open-source</h2>
|
||||
<p>Потом мы решили — ClickHouse слишком хорошая система, чтобы нам одним на нём сидеть.</p>
|
||||
<p>Чтобы было веселее, надо подсадить на ClickHouse людей снаружи, пусть радуются. Решили сделать open-source.</p>
|
||||
</section>
|
||||
<section class="slide">
|
||||
<h2>Open-source</h2>
|
||||
<p>Лицензия Apache 2.0 — минимум ограничений.</p>
|
||||
<p>Цель — максимальное распространение продукта.</p>
|
||||
<p>Мы хотим, чтобы продуктом Яндекса пользовались по всему миру.</p>

<h2>Когда надо использовать ClickHouse</h2>
|
||||
<p>Хорошо структурированные, очищенные, неизменяемые события.</p>
|
||||
<p> </p>
|
||||
<p>Click stream. Веб-аналитика. Рекламные сети. RTB. E-commerce.</p>
|
||||
<p>Аналитика онлайн игр. Данные сенсоров и мониторингов. Телеком данные.</p>
|
||||
<p>Финансовые транзакции. Биржевая аналитика.</p>

|

<section class="slide">
|

<h2 style="font-size: 40px;">Когда <span style="color:red;">не надо</span> использовать ClickHouse</h2>
|
||||
<p><span style="font-size: 30px;color: #888;">OLTP</span><br/>В ClickHouse нет UPDATE и полноценных транзакций.</p>
|
||||
<p><span style="font-size: 30px;color: #888;">Key-Value</span><br/>Если нужны частые запросы на обновление по ключу, используйте другое решение.</p>
|
||||
<p><span style="font-size: 30px;color: #888;">Blob-store, document oriented</span><br/>ClickHouse предназначен для большого количества мелко-гранулированных данных.</p>
|
||||
<p><span style="font-size: 30px;color: #888;">Излишне нормализованные данные</span><br/>Лучше сделать широкую таблицу фактов.</p>

<h2>Почему ClickHouse такой быстрый?</h2>
|
||||
<p> </p>
|
||||
<p style="font-size: 40px;">— от безысходности.</p>
|
||||
<p style="font-size: 40px;">Яндекс.Метрика должна работать.</p>
|

</section>
|
||||
<section class="slide">
|
||||
<h2>Почему ClickHouse такой быстрый?</h2>
|
||||
<p><b>Алгоритмическая оптимизация.</b></p>
|
||||
<p>MergeTree, локальность расположения данных на диске<br/>— быстрые диапазонные запросы.</p>
|
||||
<p>Пример: функция uniqCombined состоит из комбинации трёх различных структур данных, подходящих под разные диапазоны кардинальностей.</p>
|
||||
<p><b>Низкоуровневая оптимизация.</b></p>
|
||||
<p>Пример: vectorized query execution.</p>
|
||||
<p><b>Специализация и внимание к деталям.</b></p>
|
||||
<p>Пример: у нас есть 17 разных алгоритмов выполнения GROUP BY. Для вашего запроса выбирается лучший.</p>

<h2 style="font-size: 40px;">ClickHouse vs. typical row-oriented DBMS</h2>
|
||||
<p>Itai Shirav:<br /><br />«I haven't made a rigorous comparison, but I did convert a time-series table with 9 million rows from Postgres to ClickHouse.</p>
|
||||
<p>Under ClickHouse queries run about 100 times faster, and the table takes 20 times less disk space. Which is pretty amazing if you ask me».</p>

<h2>About me</h2>
|
||||
<p>Alexey, developer of ClickHouse.</p>
|
||||
<p>I work on data processing engine of Yandex.Metrica since 2008.</p>
|
||||
</section>
|
||||
<section class="slide">
|
||||
<h2>The history</h2>
|
||||
<p>Yandex.Metrica (https://metrica.yandex.com/) is a service for web analytics.</p>
|
||||
<p>Largest in Russia, second largest in the world (just after Google Analytics).</p>
|
||||
<p><img src="pictures/metrika_market_share.png"/></p>
|
||||
<p>We are processing about ~25 billions of events (page views, conversions, etc).</p>
|
||||
<p>We must generate and show reports in realtime.</p>
|
||||
</section>
|
||||
<section class="slide">
|
||||
<h2>The old Metrica (RIP 2008–2014)</h2>
|
||||
<p>Everything was working fine. User could show about 50 different reports.</p>
|
||||
<p>But there was a problem. We want more than just 50 pre-defined reports. We need to make every report infinitely customizable. The user must be able to slice and dice, and drill down every report from summary up to show single visitors.</p>
|
||||
</section>
|
||||
<section class="slide">
|
||||
<h2>The report builder</h2>
|
||||
<p>We had quickly made a prototype of so-called "report builder".</p>
|
||||
<p>This was 2010 year. It was just simple specialized column-oriented data structure.</p>
|
||||
<p>It worked fine and we got understanding, what the right direction to go.</p>
|
||||
<p>We need good column-oriented DBMS.</p>
|
||||
</section>
|
||||
<section class="slide">
|
||||
<h2>Why column-oriented?</h2>
|
||||
<p>This is how "traditional" row-oriented databases work:</p>

<h2>Why column-oriented?</h2>
|
||||
<p>And this is how column-oriented databases work:</p>
|
||||
<p><img src="pictures/column_oriented.gif"/></p>
|
||||
</section>
|
||||
<section class="slide">
|
||||
<h2>Why ClickHouse?</h2>
|
||||
<p>In 2011 there was nothing suitable in the marked. In fact there is nothing comparable even now.</p>
|
||||
<p>Then we developed ClickHouse.</p>
|
||||
<p>See nice article «Evolution of data structures in Yandex.Metrica»</p>

<li>linearly scalable</li>

<li>fault-tolerant</li>
|

<li>data ingestion in realtime</li>
|
||||
<li>realtime (sub-second) queries</li>
|

<li>support of SQL dialect + extensions<br/>(arrays, nested data types, domain-specific functions, approximate query execution)</li>

<h2>The main cluster of Yandex.Metrica</h2>
|
||||
<ul style="font-size:30px;">
|
||||
<li>18.3 trillions of rows (as of Nov 2016)</li>
|
||||
<li>426 servers</li>
|
||||
<li>total throughput of query processing is up to two terabytes per second</li>
|

</ul>
|

<p style="font-size:60%; margin-top:2em">* If you want to try ClickHouse, one server or VM is enough.</p>

<h2>ClickHouse in Yandex</h2>
|
||||
<p>Surprisingly, ClickHouse appears to be rather convenient and handy for usage.</p>
|
||||
<p>We have descriptive documentation from the beginning.</p>
|
||||
<p>In about two years, many other departments in Yandex had started to use ClickHouse in production.</p>
|
||||
<p>Yandex.Mail, Comparison shopping, Ads, Webmaster tools, Infrastructure monitoring, Business analytics, etc...</p>
|
||||
<p>There was even cases, when single analysts install ClickHouse on their VMs and started to use it without any questions.</p>
|
||||
</section>
|
||||
<section class="slide">
|
||||
<h2>Open-source</h2>
|
||||
<p>Then we decided — ClickHouse is just too good to be used solely by Yandex.</p>
|
||||
<p>To just have more fun, we need to make more companies and people around the world using ClickHouse, to let them be happy. We decided to be open-source.</p>
|
||||
</section>
|
||||
<section class="slide">
|
||||
<h2>Open-source</h2>
|
||||
<p>Apache 2.0 licence — very unrestrictive.</p>
|
||||
<p>The goal — maximum widespread of ClickHouse.</p>
|
||||
<p>We want for product by Yandex to be used everywhere.</p>

||||

<h2>When to use ClickHouse</h2>
|
||||
<p>For well structured, clean, immutable events.</p>
|
||||
<p> </p>
|
||||
<p>Click stream. Web analytics. Adv. networks. RTB. E-commerce.</p>
|
||||
<p>Analytics for online games. Sensor and monitoring data. Telecom data.</p>
|
||||
<p>Stock exchanges. Financial transactions.</p>

<h2 style="font-size: 40px;">When <span style="color:red;">not</span> to use ClickHouse</h2>
|
||||
<p><span style="font-size: 30px;color: #888;">OLTP</span><br/>ClickHouse doesn't have UPDATE statement and full-featured transactions.</p>
|
||||
<p><span style="font-size: 30px;color: #888;">Key-Value</span><br/>If you want high load of small single-row queries, please use another system.</p>
|
||||
<p><span style="font-size: 30px;color: #888;">Blob-store, document oriented</span><br/>ClickHouse is intended for vast amount of fine-grained data.</p>
|
||||
<p><span style="font-size: 30px;color: #888;">Over-normalized data</span><br/>Better to make up single wide fact table with pre-joined dimensions.</p>

<h2>Why ClickHouse is so fast?</h2>
|
||||
<p> </p>
|
||||
<p style="font-size: 40px;">— we just cannot make it slower.</p>
|
||||
<p style="font-size: 40px;">Yandex.Metrica must work.</p>
|
||||
</section>
|
||||
<section class="slide">
|
||||
<h2>Why ClickHouse is so fast?</h2>
|
||||
<p><b>Algorithmic optimizations.</b></p>
|
||||
<p>MergeTree, locality of data on disk<br/>— fast range queries.</p>
|
||||
<p>Example: uniqCombined function is a combination of three different data structures, used for different ranges of cardinalities.</p>
|
||||
<p><b>Low-level optimizations.</b></p>
|
||||
<p>Example: vectorized query execution.</p>
|
||||
<p><b>Specialization and attention to detail.</b></p>
|
||||
<p>Example: we have 17 different algorithms for GROUP BY. Best one is selected for your query.</p>

<h2 style="font-size: 40px;">ClickHouse vs. typical row-oriented DBMS</h2>
|
||||
<p>Itai Shirav:<br /><br />«I haven't made a rigorous comparison, but I did convert a time-series table with 9 million rows from Postgres to ClickHouse.</p>
|
||||
<p>Under ClickHouse queries run about 100 times faster, and the table takes 20 times less disk space. Which is pretty amazing if you ask me».</p>
