Jonathan Ellis resolved CASSANDRA-5033. --------------------------------------- Resolution: Later Pretty sure reducing write timeouts (and hence queued mutations) has fixed this. > Keep intransit mutation tracking off heap > ----------------------------------------- > > Key: CASSANDRA-5033 > URL: https://issues.apache.org/jira/browse/CASSANDRA-5033 > Project: Cassandra > Issue Type: New Feature > Components: Core > Affects Versions: 1.1.0 > Reporter: T Jake Luciani > > When a node is down and writes are timing out to that node the coordinator > keeps the mutation in memory and writes out the hint on timeout. > The problem is under heavy write load these mutations pile up quite a bit > (when CL is low). It causes a lot of heap pressure and causes a lot of > problems (which shouldn't happen just because a node is down) > If we serialized the mutation and put it in a off heap cache vs on head we > could avoid this problem. -- This message was sent by Atlassian JIRA (v6.1#6144)
