[jira] [Commented] (CASSANDRA-3595) Explore using simple byte
comparison for secondary indexes row instead partitioner ordered
[ https://issues.apache.org/jira/browse/CASSANDRA-3595?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13165332#comment-13165332 ]
Jonathan Ellis commented on CASSANDRA-3595:
-------------------------------------------
The reason we order by partitioner is so that we can give results back in that order, which is necessary to do pagination across multiple nodes.

> Key: CASSANDRA-3595
> URL: https://issues.apache.org/jira/browse/CASSANDRA-3595
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Reporter: Sylvain Lebresne
> Priority: Minor
>
> As remarked on CASSANDRA-3545, I don't think we absolutely need to have the row sorted by the partitioner for secondary indexes. And calculating hashes takes a significant amount of time (even if we take a faster hash: CASSANDRA-3594)
