<p>Let's get started with sample dataset from open sources. We will use USA civil flights data since 1987 till 2015.
It's hard to call this sample a Big Data (contains 166 millions rows, 63 Gb of uncompressed data) but this
allows us to quickly get to work. Dataset is available for download <a href="https://yadi.sk/d/pOZxpa42sDdgm">here</a>.
Also you may download it from the original datasource <a

a cluster with support for sharding and replication.</p>

incremental sort of table data. This allows fast execution of queries in ranges of a primary key.</p>

would be to count impressions for a specific Advertiser ID. This means that table primary key should start with

that you may retry insert of the same data block (possibly on a different replicas) but this block will be
inserted just once. Anyway in this guide we will load data from our localhost so we may not take care about data
blocks generation and exactly-once semantics.</p>
<p>INSERT query into tables of MergeTree type is non-blocking (so does a SELECT query). You can execute SELECT
queries right after of during insert operation.</p>
<p>Our sample dataset is a bit not optimal. There are two reasons.</p>
<p>The first is that String data type is used in cases when <a

<p class="tip"><b></b> When set of possible values is determined and known to be small. (E.g. OS name, browser
vendors etc.) it's&nbsp;recommended to use Enums or numbers to improve performance.
When set of possible values is not limited (search&nbsp;query, URL, etc.) just go ahead with String.</p>
<p>The second is that dataset contains redundant fields like Year, Quarter, Month, DayOfMonth, DayOfWeek. In fact a
single FlightDate would be enough. Most likely they have been added to improve performance for other DBMS'es
which DateTime handling functions may be not efficient.</p>

Creating a local table:
<pre>CREATE TABLE ontime_local (...) ENGINE = MergeTree(FlightDate, (Year, FlightDate), 8192);</pre>
Creating a distributed table providing a view into local tables of the cluster:
<pre>CREATE TABLE ontime_all AS ontime_local
ENGINE = Distributed(perftest_3shards_1replicas, default, ontime_local, rand());</pre>
<p>You can create a Distributed table on all machines in the cluster. This would allow to run distributed queries on
any machine of the cluster. Besides distributed table you can also use <a

<p>You may have noticed that quantiles calculation are slightly different. This happens due to <a
href="https://github.com/tdunning/t-digest/raw/master/docs/t-digest-paper/histo.pdf">t-digest</a>
algorithm implementation which is non-deterministic — it depends on the order of data processing.</p>
</div>
</div>
<p>In this case we have used a cluster with 3 shards each contains a single replica.</p>
<p>To provide for resilience in production environment we recommend that each shard should contain 2-3 replicas
distributed between multiple data-centers. Note that ClickHouse supports unlimited number of replicas.</p>
<div class="spoiler"><a class="spoiler_title">Config for cluster of one shard containing three replicas</a>

</div>
<p>To enable replication <a href="http://zookeeper.apache.org/" rel="external nofollow">ZooKeeper</a> is required.
ClickHouse will take care of data consistency on all replicas and run restore procedure after failure
automatically. It's recommended to deploy ZooKeeper cluster to separate servers.</p>

<p>ZooKeeper is not a requirement — in some simple cases you can duplicate the data by writing it into all the
replicas from your application code. This approach is not recommended — in this case ClickHouse is not able to
guarantee data consistency on all replicas. This remains the responsibility of your application.</p>
<div class="spoiler"><a class="spoiler_title">Set ZooKeeper locations in configuration file</a>
<div class="spoiler_body">
<pre>
&lt;zookeeper-servers&gt;
&lt;node&gt;
&lt;host&gt;zoo01.yandex.ru&lt;/host&gt;
&lt;port&gt;2181&lt;/port&gt;
&lt;/node&gt;
&lt;node&gt;
&lt;host&gt;zoo02.yandex.ru&lt;/host&gt;
&lt;port&gt;2181&lt;/port&gt;
&lt;/node&gt;
&lt;node&gt;
&lt;host&gt;zoo03.yandex.ru&lt;/host&gt;
&lt;port&gt;2181&lt;/port&gt;
&lt;/node&gt;
&lt;/zookeeper-servers&gt;
</pre>
</div>
</div>
<p>Also we need to set macros for identifying shard and replica — it will be used on table creation</p>
<pre>
&lt;macros&gt;
&lt;shard&gt;01&lt;/shard&gt;
&lt;replica&gt;01&lt;/replica&gt;
&lt;/macros&gt;
</pre>
<p>If there are no replicas at the moment on replicated table creation — a new first replica will be instantiated.
If there are already live replicas — new replica will clone the data from existing ones. You have an option to
create all replicated tables first and that insert data to it. Another option is to create some replicas and add
the others after or during data insertion.</p>
<pre>
CREATE TABLE ontime_replica (...)
ENGINE = ReplicatedMergeTree(
'/clickhouse_perftest/tables/{shard}/ontime',

table type. In parameters we specify ZooKeeper path containing shard and replica identifiers.</p>
<pre>INSERT INTO ontime_replica SELECT * FROM ontime;</pre>
<p>Replication operates in multi-master mode. Data can be loaded into any replica — it will be synced with other
instances automatically. Replication is asynchronous so at a given moment of time not all replicas may contain
recently inserted data. To allow data insertion at least one replica should be up. Others will sync up data and
repair consistency once they will become active again. Please notice that such scheme allows for the possibility
of just appended data loss.</p>
