How to check your ClickHouse version

ClickHouse is an open-source columnar database designed for high-performance analytical queries. Knowing your version is crucial due to significant differences between versions, including breaking changes and performance variations. To check the ClickHouse version, you can use SQL with a simple query (`SELECT version()`), access the HTTP endpoint by sending a GET request to `https://your_clickhouse_server:8123/?query=SELECT+version()`, or utilize the Prometheus endpoint by querying the relevant metric (`http://<your_clickhouse_server>:<port>/metrics` | grep clickhouse_build_info). These methods offer flexibility and efficiency for teams operating ClickHouse in production.
