One of the gotchas I just experienced upgrading to signoz v0.23.0 is that Helm does not upgrade CRDs, so my clickhouse cluster lost a node. https://helm.sh/docs/chart_best_practices/custom_resource_definitions/
You get warnings like this in the operator, referring to fields that are not in the installed CRD:
W0714 153701.316359 1 warnings.go:70] unknown field "status.hostsWithTablesCreated"
W0714 153701.316370 1 warnings.go:70] unknown field "status.pod-ips"
I ended up having to git clone the charts, manually apply the CRDs and then restart the operator
