ClickHouse

The Hydrolix system is a data lake solution built on top of the ClickHouse engine. Most ClickHouse tools interoperate with the Hydrolix query system.

ClickHouse native protocol

The Native interface supports any clients or client libraries capable of the ClickHouse native protocol. Use tunable disable_traefik_native_port to turn off the server.

Example ClickHouse native connection

$ clickhouse-client -h {myhost}.hydrolix.live --port 9440 -u '[email protected]' -s
ClickHouse client version 25.3.2.39 (official build).
Connecting to {myhost}.hydrolix.live:9440 as user [email protected].
Password for user ([email protected]): 
Connecting to {myhost}.hydrolix.live:9440 as user [email protected].
Connected to ClickHouse server version 24.8.6.

ClickHouse server version is older than ClickHouse client. It may indicate that the server is out of date and can be upgraded.

Hydrolix ClickHouse engine versioning

Your ClickHouse client may report server version mismatch. The Hydrolix fork of the ClickHouse engine follows upstream, so isn't synchronized.
