Deprecated. Use the one from StreamingDeveloperConfig instead.

enable_state_cleaning: bool

Whether the executor is allowed to clean up state rows in recently touched partitions that can never be accessed again, driven by the watermark on the first order_by column. The optimizer only enables this when the input is append-only, all window frames are bounded ROWS frames, and the first order_by column is a watermark column.
