---------------------------------------
Summary: TriggerExecutor should group mutations by row key
Key: CASSANDRA-7047
URL: https://issues.apache.org/jira/browse/CASSANDRA-7047
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Sergio Bossa
Assignee: Sergio Bossa
TriggerExecutor doesn't currently group mutations returned by triggers even if
belonging to the same row key: while harmful per se (at least, I think so),
this is definitely a performance problem, because each mutation is a *cluster*
mutation, generating more network traffic, more disk IO and more index calls
(if present).
