I am having trouble connecting to clickhouse running locally in docker image. I am using version "1.0.0-alpha.1". I get following error:

Error: Io(Custom { kind: Other, error: "Driver error: `Unknown packet 0x48.`" })

when calling this part of code:

    let pool = Pool::new("tcp://localhost:8124?compression=lz4");
    let mut client = pool.get_handle().await?;

Try to use tcp://localhost:9000?compression=lz4

yes, its working now, but its bypassing chproxy

suharev7 commented 10 months ago

clickhouse-rs works with binary protocol (by default port: 9000) and chproxy works with HTTP protocol (by default port: 8123), so:

If you would like to work through binary protocol with multiple clickhouse instances, you may specify multiple hosts in url: tcp://host1:9000?alt_hosts=host2:9000,host3:9000
If you would like to work through the HTTP protocol with chproxy you need to use http clickhouse client library, for example https://crates.io/crates/clickhouse
