Timo Walther commented on FLINK-24254:
--------------------------------------
Another symptom of this issue is
{{FileSystemConnectorOptions.SINK_SHUFFLE_BY_PARTITION}}. It mixes connector
options with sink-topology planner options in {{BatchPhysicalSinkRule}}.
> Support configuration hints for table sources and sinks
> -------------------------------------------------------

> Key: FLINK-24254
> URL: https://issues.apache.org/jira/browse/FLINK-24254
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / API
> Reporter: Timo Walther
> Priority: Major
>
> We currently offer config option that modify the behavior of sources and
> sinks. Such as:
> {code}
> table.exec.source.cdc-events-duplicate
> table.exec.sink.not-null-enforcer
> table.exec.sink.upsert-materialize
> {code}
> Instead of defining them globally, it should be possible to set them more
> fine-grained via hints. Either we reuse the {{OPTIONS(key=value, ...)}} hint,
> or come up with new category such as {{CONFIG(key=value, ...)}} to not mix
> table factory options with configuration.
