waittting commented on FLINK-25149:
-----------------------------------
Thank you for your reply, but in my code the constructor method of
CCDynamicSourceFunction is called every time when the getScanRuntimeProvider be
called, is this the correct phenomenon?
> getScanRuntimeProvider method called before the pushDown method,
> ----------------------------------------------------------------

> public class CCDynamicTableSource implements ScanTableSource,
> SupportsLimitPushDown, SupportsFilterPushDown, SupportsProjectionPushDown {}
