Queue indexes for flush before the parent
-----------------------------------------
Key: CASSANDRA-2330
URL: https://issues.apache.org/jira/browse/CASSANDRA-2330
Project: Cassandra
Issue Type: Improvement
Components: Contrib
Affects Versions: 0.7.1
Reporter: Brandon Williams
Assignee: Brandon Williams
Priority: Minor
Fix For: 0.7.4
Secondary indexes flush when the parent does. This has an unfortunate side
effect: a single CF flushing with a single secondary index fills the flush
queue and blocks further writes until the first one completes. A simple but
naive optimization here would be to queue the indexes before the parent since
they are generally going to be smaller, and thus flush faster, reducing the
amount of time writes are blocked.
