T Jake Luciani updated CASSANDRA-8639: -------------------------------------- Fix Version/s: (was: 2.1.x) 3.2 > Can OOM on CL replay with dense mutations > ----------------------------------------- > > Key: CASSANDRA-8639 > URL: https://issues.apache.org/jira/browse/CASSANDRA-8639 > Project: Cassandra > Issue Type: Improvement > Components: Local Write-Read Paths > Reporter: T Jake Luciani > Assignee: Ariel Weisberg > Priority: Minor > Fix For: 3.2 > > > If you write dense mutations with many clustering keys, the replay of the CL > can quickly overwhelm a node on startup. This looks to be caused by the fact > we only ensure there are 1000 mutations in flight at a time. but those > mutations could have thousands of cells in them. > A better approach would be to limit the CL replay to the amount of memory in > flight using cell.unsharedHeapSize() -- This message was sent by Atlassian JIRA (v6.3.4#6332)
