What was ClickHouse used for?

ClickHouse is a columnar DBMS optimized for analytical queries and processing large volumes of data in real-time. In Flutter projects, ClickHouse is typically used for storing and analyzing large sets of logs, metrics, or user data, which can then be quickly aggregated and visualized.

Example of use: an application collects user events (clicks, views), sends them to a server, where the data is stored in ClickHouse for subsequent analysis and reporting on user behavior.
