Jonathan Ellis updated CASSANDRA-9041:
--------------------------------------
Assignee: Sam Tunnicliffe
> Allow a PerRowSecondaryIndex to perform its 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
> Assignee: Sam Tunnicliffe
>
> 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.
