<p>ClickHouse uses all available hardware to its full potential to process each query as fast as possible. The peak

<p>In contrast to common data management methods, where vast amounts of raw data in its native format are available as

a "data lake" for any given query,

ClickHouse offers instant results in most cases: the data is processed faster than it takes

to create a query. Follow the link below to see detailed benchmarks by Yandex of ClickHouse in comparison

<h2 id="linearly-scalable">Linearly Scalable</h2>
|
||
|
||
<p>ClickHouse allows companies to add servers to their clusters when necessary without investing time or money into
|
||
any additional DBMS modification. The system has been successfully serving
|
||
<a href="https://metrica.yandex.com/" rel="external nofollow">Yandex.Metrica</a>,
|
||
while the count of servers in it's main production cluster have grown from 60 to 394 in two years,
|
||
which are by the way located in six geographically distributed datacenters.</p>
|
||
|
||
<p>ClickHouse scales well both vertically and horizontally. ClickHouse is easily adaptable to perform either on
|
||
cluster with hundreds of nodes, or on a single server or even on a tiny virtual machine. Currently there are
|
||
installations with more than two trillion rows per single node,
|
||
as well as installations with 100Tb of storage per single node.</p>
|
||
|
||
|
||
<h2 id="hardware-efficient">Hardware Efficient</h2>
|
||
|
||
<p>ClickHouse processes typical analytical queries two to three orders of magnitude faster than traditional
|
||
row-oriented systems with the same available I/O throughput. The system's columnar storage format allows fitting
|
||
more hot data in RAM, which leads to a shorter response times.</p>
|
||
|
||
<p>ClickHouse allows to minimize the number of seeks for range queries, which increases efficiency of using rotational
|
||
disk drives, as it maintains locality of reference for continually stored data.</p>
|
||
|
||
<p>ClickHouse is CPU efficient because of it's vectorized query execution involving relevant processor instructions
|
||
and runtime code generation.</p>
|
||
|
||
<p>By minimizing data transfers for most types of queries, ClickHouse enables companies to manage their data and
|
||
create reports without using specialized networks that are aimed at high-performance computing.</p>
|
||
|
||
<h2 id="fault-tolerant">Fault Tolerant</h2>
|
||
|
||
<p>ClickHouse supports multi-master asynchronous replication and can be deployed across multiple datacenters.
|
||
Downtime of a single node or the whole datacenter won't affect the system's availability for both reads and
|
||
writes.
|
||
Distributed reads are automatically balanced to live replicas to avoid increasing latency. Replicated data
|
||
are synchronized automatically or semi-automatically after server downtime.</p>

<h2 id="feature-rich">Feature Rich</h2>
|
||
|
||
<p>ClickHouse features a user-friendly SQL query dialect with a number of built-in analytics capabilities.
|
||
For example, it includes probabilistic data
|
||
structures for fast and memory-efficient calculation of cardinalities and quantiles. There are functions for
|
||
working dates, times and time zones, as well as some specialized ones like addressing URLs and IPs
|
||
(both IPv4 and IPv6) and many more.</p>
|
||
|
||
<p>Data organizing options available in ClickHouse, such as arrays, array joins, tuples and nested data structures, are
|
||
extremely efficient for managing denormalized data.</p>
|
||
|
||
<p>Using ClickHouse allows joining both distributed data and co-located data, as the system supports local joins and
|
||
distributed joins. It also offers an opportunity to use external dictionaries, dimension tables loaded from
|
||
an external source, for seamless joins with simple syntax.</p>
|
||
|
||
<p>ClickHouse supports approximate query processing – you can get results as fast as you want, which is
|
||
indispensable when dealing with terabytes and petabytes of data.</p>
|
||
|
||
<p>The system's conditional aggregate functions, calculation of totals and extremes, allow getting results with a
|
||
single query without having to run a number of them.</p>

<h2>When to use ClickHouse</h2>
|
||
|
||
<p>For analytics over stream of clean, well structured and immutable events or logs.
|
||
It is recommended to put each such stream into a single wide fact table with pre-joined dimensions.
|
||
</p>
|
||
<p>Some examples of viable applications:</p>
|
||
|
||
<ul class="dashed">
|
||
<li>Web and App analytics</li>
|
||
<li>Advertising networks and RTB</li>
|
||
<li>Telecommunications</li>
|
||
<li>E-commerce and finance</li>
|
||
<li>Information security</li>
|
||
<li>Monitoring and telemetry</li>
|
||
<li>Time series</li>
|
||
<li>Business intelligence</li>
|
||
<li>Online games</li>
|
||
<li>Internet of Things</li>
|
||
</ul>
|
||
|
||
<h2>When <span class="red">NOT</span> to use ClickHouse</h2>
|
||
|
||
<ul class="dashed">
|
||
<li>Transactional workloads (OLTP)</li>
|
||
<li>Key-value access with high request rate</li>
|
||
<li>Blob or document storage</li>
|
||
<li>Over-normalized data</li>
|
||
</ul>

<h2 id="highly-reliable">Highly Reliable</h2>
|
||
|
||
<p>ClickHouse has been managing petabytes of data serving a number of highload mass audience services of
|
||
<a href="https://www.yandex.com/company/"
|
||
rel="external nofollow">Yandex</a>, Russia's
|
||
leading search provider and one of largest European IT companies.
|
||
Since 2012, ClickHouse has been providing robust database management for the company's <a
|
||
href="https://metrica.yandex.com/" rel="external nofollow">web analytics service</a>, comparison
|
||
e-commerce platform, public email service, online advertising platform, business intelligence tools
|
||
and infrastructure monitoring.</p>
|
||
|
||
<p>ClickHouse can be configured as purely distributed system located on independent nodes,
|
||
without any single points of failure.</p>
|
||
|
||
<p>Software and hardware failures or misconfigurations do not result in loss of data. Instead of deleting "broken"
|
||
data, ClickHouse saves it or asks you what to do before a startup. All data is checksummed before every
|
||
read or write to disk or network. It is virtually impossible to delete data by accident as there are safeguards
|
||
even for human errors.</p>
|
||
|
||
<p>ClickHouse offers flexible limits on query complexity and resource usage, which can be fine-tuned with settings.
|
||
It is possible to simultaneously serve both a number of high priority low-latency requests and some
|
||
long-running queries with background priority.</p>
|
||
|
||
<h2 id="simple-and-handy">Simple and Handy</h2>
|
||
<p>ClickHouse streamlines all your data processing. It's easy to use: ingest all your structured data into the
|
||
system, and it is instantly available for reports. New columns for new properties or dimensions can be
|
||
easily added to the system at any time without slowing it down.</p>
|
||
|
||
<p>ClickHouse is simple and works out-of-the-box. As well as performing on hundreds of node clusters, this system
|
||
can be easily installed on a single server or even a virtual machine. No development experience or code-writing
|
||
skills are required to install ClickHouse.</p>
