Dongjoon Hyun updated SPARK-30244:
----------------------------------
Affects Version/s: (was: 3.0.0)
3.1.0
> Emit pre/post events for "Partition" methods in ExternalCatalogWithListener
> ---------------------------------------------------------------------------
>
> Key: SPARK-30244
> URL: https://issues.apache.org/jira/browse/SPARK-30244
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Jackson Westeen
> Priority: Major
>
> Many of the methods in `ExternalCatalogWithListener` support emitting
> pre/post events to the ListenerBus when delegating calls to the underlying
> ExternalCatalog implementation.
> Is there a reason the "Partition" series of methods don't support this
> feature?
> [https://github.com/apache/spark/blob/v2.4.4/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/catalog/ExternalCatalogWithListener.scala#L193]
> We're looking to hook into post "ALTER TABLE ADD PARTITION" calls, so we can
> publish a message to Kafka for example, whenever new partitions are added to
> the metastore.
> It appears there's already event hooks for createDatabase / createTable.. but
> not createPartition. Would you consider adding hooks here? Or is there a
> better way to hook into to successful "ALTER TABLE ADD PARTITION" calls and
> subscribe to changes in partition status?
> Thank you!
