Jackey Lee commented on SPARK-31694:
------------------------------------
Hi [~younggyuchun]
Thank you for your attention
Basically, a new TablePartition is defined to store partition information, and
then use the partition catalog API, abstracted from the ExternalCatalog, to
access these partitions.
> Add SupportsPartitions Catalog APIs on DataSourceV2

> Key: SPARK-31694
> URL: https://issues.apache.org/jira/browse/SPARK-31694
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Jackey Lee
> Priority: Major
>
> There are no partition Commands, such as AlterTableAddPartition supported in
> DatasourceV2, it is widely used in mysql or hive or other places. Thus it is
> necessary to defined Partition Catalog API to support these Commands.
> We add SupportsPartitions to use basic APIs to support these commands.
