Staggering repair
-----------------
Key: CASSANDRA-3721
URL: https://issues.apache.org/jira/browse/CASSANDRA-3721
Project: Cassandra
Issue Type: Improvement
Components: Core
Affects Versions: 1.1
Reporter: Vijay
Assignee: Vijay
Priority: Minor
Currently repair runs on all the nodes at once and causing the range of data to
be hot (higher latency on reads).
Sequence:
1) Send a repair request to all of the nodes so we can hold the references of
the SSTables (point at which repair was initiated)
2) Send Validation on one node at a time (once completed will release
references).
3) Hold the reference of the tree in the requesting node and once everything is
complete start diff.
We can also serialize the streaming part not more than 1 node is involved in
the streaming.
