What is surprising: if you query MySQL from ClickHouse, the queries work faster despite the fact that the data is simply read from MySQL. And two more use-cases:
- you can create a table in ClickHouse pointing to multiple MySQL servers for sharding and failover, so ClickHouse can be used to query sharded MySQL;
- you can create a key-value dictionary on top of MySQL tables and use it in JOINs. |
