[jira] [Updated] (CASSANDRA-5220) Repair improvements when using vnodes

This appears at least in part because it's using a session per range and processing them sequentially. This generates a lot of log spam with vnodes, and while being gentler and lighter on hard disk deployments, ssd-based deployments would often prefer that repair be as fast as possible. -- This message was sent by Atlassian JIRA (v6.3.4#6332)

[ https://issues.apache.org/jira/browse/CASSANDRA-5220?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Marcus Olsson updated CASSANDRA-5220: - Attachment: cassandra-3.0-5220-2.patch With this patch the dtest works for me, both with vnodes and without. There was a problem with wrap around ranges and the merkle tree iterator I made that only occurred if there was data around both the min and max tokens. The problem was that it had already iterated over the merkle tree for the wrap around range in the beginning, so the solution I chose was to reiterate over the merkle trees in Validator.add() if the end was reached. With the patch applied I saw a ~4 seconds improvement(from ~18 to ~14) when using vnodes. Without vnodes it took around 10-11 seconds.

Old Time is without vnodes, New Time is with vnodes.
