[jira] [Created] (CASSANDRA-2914) Simplify HH to always store hints
on the coordinator
Simplify HH to always store hints on the coordinator
----------------------------------------------------
Key: CASSANDRA-2914
URL: https://issues.apache.org/jira/browse/CASSANDRA-2914
Project: Cassandra
Issue Type: Improvement
Components: Core
Affects Versions: 1.0
Reporter: Jonathan Ellis
Assignee: Patricio Echague
Fix For: 1.0
Moved from CASSANDRA-2045:
Since we're storing the full mutation post-2045, there's no benefit to be gained from storing the hint on the replica node, only an increase in complexity. Let's switch it to always store hints on the coordinator instead.
