Stefania commented on CASSANDRA-9318: ------------------------------------- Thanks [~sbtourist], the latest commits and the entire patch LGTM. The test failures are all unrelated and we have tickets for all of them: CASSANDRA-12664, CASSANDRA-12656 and CASSANDRA-12140. I've launched one more dtest build to cover the final commit and to hopefully shake off the CASSANDRA-12656 failures since these tests shouldn't even be running now. I've squashed your entire patch into [one commit|https://github.com/stef1927/cassandra/commit/1632f2e9892624f611ac3629fb84a82594fec726] and fixed some formatting issues (mostly trailing spaces) [here|https://github.com/stef1927/cassandra/commit/e3346e5f5a49b2933e10a84405730] on this [branch|https://github.com/stef1927/cassandra/commits/9318]. If you could double check the formatting nits, I can squash them and commit once the final dtest build has also completed. > Bound the number of in-flight requests at the coordinator > --------------------------------------------------------- > > Key: CASSANDRA-9318 > URL: https://issues.apache.org/jira/browse/CASSANDRA-9318 > Project: Cassandra > Issue Type: Improvement > Components: Local Write-Read Paths, Streaming and Messaging > Reporter: Ariel Weisberg > Assignee: Sergio Bossa > Attachments: 9318-3.0-nits-trailing-spaces.patch, backpressure.png, > limit.btm, no_backpressure.png > > > It's possible to somewhat bound the amount of load accepted into the cluster > by bounding the number of in-flight requests and request bytes. > An implementation might do something like track the number of outstanding > bytes and requests and if it reaches a high watermark disable read on client > connections until it goes back below some low watermark. > Need to make sure that disabling read on the client connection won't > introduce other issues. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
