Jack Krupansky commented on CASSANDRA-7047: ------------------------------------------- Is the description correct? It says: bq. ... while harmful per se (at least, I think so) But shouldn't that be "not harmful per se"? > 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 > Attachments: 7047-v2.txt, CASSANDRA-7047.patch > > > 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)
