Jay Ghiya created FLINK-26793:
---------------------------------

             Summary: Flink Cassandra connector performance issue 
                 Key: FLINK-26793
                 URL: https://issues.apache.org/jira/browse/FLINK-26793
             Project: Flink
          Issue Type: Improvement
          Components: Connectors / Cassandra
    Affects Versions: 1.14.4
            Reporter: Jay Ghiya


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”
