Hi! Thank you for great crate!

Once a second in the logs such an error:

http connect, over 1Gb network between servers, load average: 0.95, 1.15, 1.20 on 16 cpu server.

What would you recommend to do on the client?

Hello, do you have some minimal example for this?

That's most likely clickhouse bug:
