Hi Abhilasha, We were conservative about enabling this by default to prevent any unexpected problems. However, since there has been no reported issues so far, we will enable this by default in 1.10.0 release. Please refer to FLINK-14898 [1], FLINK-15506 [2] and (currently drafted) 1.10.0 release note [3] for more details
