Summary: Can OOM on CL replay with dense mutations Key: CASSANDRA-8639 URL: https://issues.apache.org/jira/browse/CASSANDRA-8639 Project: Cassandra Issue Type: Bug Reporter: T Jake Luciani Priority: Minor Fix For: 2.1.3 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)
