<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
|
|

|
|
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>
