Hi: When the stream is joined with another stream , the cached stream data will be saved as a state and deleted as the watermark advances. I found that there is also a parameter that can set the state expiration time, such as StateTtlConfig in DataStream APIļ¼ TableConfig in TableAPI &SQL .This setting is effective for the state of group by operator. And now the state TTL seems to be based on processing time.If the configured TTL has been reached and the watermark has not moved to the edge. The state of join will be cleared ? What is the relationship between StateTtlConfig and TableConfig? If I use StateTtlConfig and program with TableAPI, can the configuration take effect?
