> 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”
