What volumes of data were processed in ClickHouse?

The data volumes that entered ClickHouse depended on the specific project, but they were usually large streams of events and logs with high generation speed — from several million to hundreds of millions of records per day.

For example, in one project, we collected data on user actions on the website and mobile applications, which amounted to about 50-100 million events per day. ClickHouse allowed efficient aggregation and analysis of this data in real-time thanks to its columnar architecture and high performance.

To optimize working with such volumes, partitioning by time and keys, as well as data compression, were used.
