Hi Devs, I would like to start a discussion on support configuration to disable filter pushdown for Table/SQL Sources[1].
Currently, Flink SQL does not support the ability for users to enable or disable filter pushdown. However, filter pushdown has some side effects, such as additional computational pressure on external systems. Moreover, Improper queries can lead to issues such as full table scans, which in turn can impact the stability of external systems. I propose to support configuration to disable filter push down for Table/SQL sources to let user decide whether to perform filter pushdown. Looking forward to your feedback.
