Hello, Team, As per this, zookeeper is not necessary for single node clickhouse and I do not think there's an option to not use a zookeeper in the SigNoz/ClickHouse helm chart. Any help on how to disable it and whether we even should (to save on memory) ?

It's a very lightweight container. You do not gain much by removing it.

@Srikanth Chekuri Agreed, but we have a use case where we have to reduce the entire stack within 2 GB of RAM, while we already managed to bring it down to 2.9 GB, releasing around 300 MBs used by zookeeper would help us a long way in that, Any way to do that? Thanks for your reply 👍

There would errors in ClickHouse without zookeeper

@Srikanth Chekuri Yes, but it is only failing when clickhouse is initialised in the absence of zookeeper, Once it starts, scaling zookeeper down does not make any difference, am adding a post install hook to scale zookeeper down after clickhouse is up. This approach would impair clickhouse in case of a automatic restart, but this seems to be the only way to go to save that 300MB. Any better ideas or suggestions are welcome.
