A warning is observed during long runs of flink job stating “Insertions into scylla might be suffering. Expect performance problems unless this is resolved.” Upon initial analysis - “flink cassandra connector is not keeping instance of mapping manager that is used to convert a pojo to cassandra row. Ideally the mapping manager should have the same life time as cluster and session objects which are also created once when the driver is initialized” Reference: https://stackoverflow.com/questions/59203418/cassandra-java-driver-warning -- This message was sent by Atlassian Jira (v8.20.1#820001)
