> Priority: Major
> Fix For: 4.1.0
>
>
> When a user topic which has been consumed in a share group is deleted, it is
> necessary to clean up the associated records on the share-group state topic.
> This could be driven from the GC or from the SC itself. Right now, the
> records remain forever, as do the ShareGroupStatePartitionMetadata entries
> for deleted topics. The SharePartitionManager does respond to topic deletion
> by observing metadata changes.
