--------------------------------------------
Summary: Batchlog endpoint candidates should be picked randomly,
not sorted by proximity
Key: CASSANDRA-6481
URL: https://issues.apache.org/jira/browse/CASSANDRA-6481
Project: Cassandra
Issue Type: Bug
Reporter: Aleksey Yeschenko
Assignee: Aleksey Yeschenko
Fix For: 1.2.13, 2.0.4
Attachments: 6481.txt
Batchlog endpoint candidates should be picked randomly, not sorted by
proximity. I'll be lazy and just copy-paste some lines from IRC:
[20:23:27] rbranson: is there an issue where batch logs tend to get written
to a subset of the nodes?
[20:28:04] rbranson: I mean all the write batches are going thru 10% of the
nodes
[20:28:16] rbranson: it means writes won't scale linearly w/the cluster size
Attaching a trivial patch.
