------------------------------------
Thanks Timo and Kurt, the sub-task has been resolved and we can close it now, i
think we can fire a new issue for Calcite version 1.22 and make
sub-tasks(introduced by upgrade of 1.21) there.

> Umbrella issue for all tasks related to the next Calcite upgrade to 1.21.x
> release
> Calcite 1.21 has been released recently, we need to upgrade to version 1.21
> for these reasons:
> - Previously we have made some temp code to support full data types in sql
> parser, since CALCITE-3213 has been resolved, we can do some refactoring for
> these codes;
> - We also fixed some important bug for Join which bring in from Calcite 1.20
> join like expression promotion, such as CALCITE-3170, CALCITE-3171.
> - CALCITE-2302 has been resolved, there is possibility we support implicit
> type coercion for Flink now.
