Sergio Bossa created CASSANDRA-7047: ---------------------------------------
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). -- This message was sent by Atlassian JIRA (v6.2#6252)
