Attachment: RemoveAll.pdf
> Add support for removeAllKeys
> -----------------------------
>
> Key: SPARK-27730
> URL: https://issues.apache.org/jira/browse/SPARK-27730
> Project: Spark
> Issue Type: Sub-task
> Components: Spark Core
> Affects Versions: 2.3.3
> Reporter: David C Navas
> Priority: Major
> Attachments: RemoveAll.pdf
>
>
> After a false start as described in attached, I implement a removeAllKeys
> call to KVStore that is capable of deleting all keys that match a particular
> class' index. The implementation in LevelDB performs a delete based on each
> key, as elements in LevelDB are indexed, and the implementation in
> InMemoryStore performs a scan and conditional remove, as elements in
> InMemoryStore are not indexed.
