@chhetripradeep from https://github.com/pavolloffay/jaeger-clickhouse/pull/34#issuecomment-886882402

We run with 3 replica and as we need to expand the cluster we add more shards. One thing to note is clickhouse doesn't have any inbuilt data balancing feature i.e. once a data is written to a node, it will stay there throughout the lifetime of that data unless the operator moves the data manually, so it's good to do capacity planning in the beginning of cluster provisioning.

Would you like to create a doc/guide for capacity planning?
