----------------------------------------
Summary: Warn the user on full table scans
Key: FLINK-38042
URL: https://issues.apache.org/jira/browse/FLINK-38042
Project: Flink
Issue Type: Improvement
Components: Connectors / Cassandra
Reporter: Etienne Chauchot
Assignee: Etienne Chauchot
The Cassandra source connector allows the user to specify a query. This query
can contain filters on the provided table. So these filters are pushed down but
in some cases, they could lead to inefficient table scans:
- Filtering on non-indexed, non-key columns
- not restricting on partition key leads the cluster to read all the partitions
We should detect such cases and warn the user.
