rebuild
[ https://issues.apache.org/jira/browse/CASSANDRA-11218?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16111658#comment-16111658 ]
Tania S Engel commented on CASSANDRA-11218:
-------------------------------------------
Could the index summary redistribution be the cause of the 29 minute gap in stream time for this appliance? Typically in this test for us the Prepare completed happens within the minute.

> Key: CASSANDRA-11218

> Project: Cassandra
> Issue Type: Improvement
> Components: Compaction, Secondary Indexes
> Reporter: sankalp kohli
> Assignee: Jeff Jirsa
> Priority: Minor
>
> We have seen that secondary index rebuild get stuck behind other compaction during a bootstrap and other operations. This causes things to not finish. We should prioritize index rebuild via a separate thread pool or using a priority queue.
