> The latest available version of Calcite is currently 1.30. We already need to execute the rework that was planned when upgrading to Calcite 1.27 FLINK-20873 and when upgrading to Calcite 1.28 FLINK-21239
> When doing this upgrade, we should do this to the last available version. This is needed to resolve multiple bugs. 
> Additional note: Flink currently uses Calcite 1.26.0 which has this note on the release page:
> {{Warning: Calcite 1.26.0 has severe issues with RexNode simplification caused by SEARCH operator ( wrong data from query optimization like in CALCITE-4325, CALCITE-4352, NullPointerException), so use 1.26.0 for development only, and beware that Calcite 1.26.0 might corrupt your data.}}
