Hi, @zentol , thanks for reviewing this PR. I recalled that I put a [caveat
](https://ci.apache.org/projects/flink/flink-docs-release-1.4/dev/connectors/cassandra.html#checkpointing-and-fault-tolerance)about
this potential data loss in the latest C* connector documents. Since this fix
is committed, would you like me to open another PR just to remove that warning
message from document?---
