Subject [jira] [Created] (CASSANDRA-3386) Avoid lock contention in hint rows
Date Wed, 19 Oct 2011 20:31:12 GMT
Avoid lock contention in hint rows

                 Key: CASSANDRA-3386
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
    Affects Versions: 0.7.0
            Reporter: Jonathan Ellis
            Assignee: Jonathan Ellis
             Fix For: 0.8.8, 1.0.1

As pointed out by Yang in CASSANDRA-3385, hint writes are keyed by target IP, to make replay
efficient. However, this means that we'll hit a lot of lock contention in table.apply where
we synchronize for potential index updates.
