It is complementary to "don't accept more than you can handle." > 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 > Reporter: Ariel Weisberg > Assignee: Ariel Weisberg > Fix For: 2.1.x, 2.2.x > > > 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)
