https://github.com/ClickHouse/ch-go
we used above library we received 500 qps for single node but for scalability and performance moved with replication and sharding
General query test was successful with distributed and replication
while trying load test after package based tables
just 50 qps we got above we faced timeout issue
Then as per your support team got this library
https://github.com/ClickHouse/clickhouse-go
now same issues only one node is working
replication works but distributed table not working as expected before library
is this clickhouse server setting issues or library issues

Hey can you fill out the issue template? Simply edit the issue description and fill out some of the details. It sounds like you're having performance issues, but I can't even begin to investigate without some more info.

I would continue talking to the support team too to make sure there's no issues with your cloud service's configuration.

Thanks!
