I'd like to work on this. I reproduced it on main (Flink 2.3): `RowDataWrapper` has no getters for ARRAY and MAP columns, so when `FlinkSourceFilter` applies the pushed-down `IS NOT NULL` filter, the evaluator's cast to `List`/`Map` fails on Flink's `ArrayData`/`MapData`. MAP columns and lists nested inside structs fail the same way, and so do VARIANT columns on Flink 2.x. This looks like the same root cause as #13170. I plan to add ARRAY and MAP handling to `RowDataWrapper` in v2.3 first and backport to the other Flink versions in a follow-up. cc @pvary @mxm -- This is an automated message from the Apache Git Service.
