---------------------------------
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”
