Hi, G'day everyone. Do we have documentation for upgrading pinot in kubernetes? Can anyone share it please.

Not sure about the docs , i dont see any. Regardless, upgrades for a system like pinot should be incremental ie rolling upgrades in a defined order. To achieve something like this on k8s, you would need an operator.

The upgrade order is controller -> broker -> server. Also, rolling restarts are zero-downtime as long as there’s replication > 1.
