-------------------------------------
Summary: Allow a PerRowSecondaryIndex to perform it's index
operation before the underlying data has been mutated
Key: CASSANDRA-9041
URL: https://issues.apache.org/jira/browse/CASSANDRA-9041
Project: Cassandra
Issue Type: New Feature
Components: Core
Reporter: Bryn Cooke
The current PerRowSecondaryIndex receives its index event after the call to
BTree.update. This means that it is impossible to write an index that eagerly
removes stale index entries.
It would be great to have some sort of preIndex method that gets called with
the key and column family.
In addition a postIndex method that is guaranteed to get called regardless if
the actual BTree operation succeeds or not would allow cleanup in the event of
error.
