> 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
> Priority: Major
>
> 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:
