-------------------------------------
Summary: 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
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.
