-----------------------------------
[~echauchot] [~martijnvisser]- could we take this task and split into two
activities. First being the solving the performance issue so that product
releases are not halted. and second being the migration to new api?
> 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”
