Hi Dawid,
thanks for your interest. We are currently moving the Table API on top of
Apache Calcite (see [FLINK-3221]). The code generation needed to be rewritten
for that. This issue is now more complicated than it was before (with the "old"
Table API), because the new CodeGenerator does not support the Date type at all
yet. We need to sync it with Calcites time/date types first. If you like to
work on this issue anyway I can help you integrating the Date type into the new
Table API on Calcite.
Regards,
Timo

> Currently, the Table API does not support comparisons like "DATE < DATE",
> "DATE >= DATE". The ExpressionCodeGenerator needs to be adapted for that.
