Jordan West created CASSANDRA-14782: ---------------------------------------
Summary: Large mutations can wreak havoc before being rejected by the commit log Key: CASSANDRA-14782 URL: https://issues.apache.org/jira/browse/CASSANDRA-14782 Project: Cassandra Issue Type: Bug Reporter: Jordan West Large mutations are rejected by the commit log (https://github.com/apache/cassandra/blob/cassandra-3.0/src/java/org/apache/cassandra/db/commitlog/CommitLog.java#L254) but when {{totalSize}} is significantly greater than the {{MAX_MUTATION_SIZE}} the damage to the node may already done. Large mutations cause large buffers to be allocated and can lead to GC trashing and generally bad node health. It should be possible to set a size above which the native protocol rejects messages without materializing them into objects and passing them downstream. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
