Chris Gerlt commented on CASSANDRA-10256: ----------------------------------------- Since the code has: MAX_MUTATION_SIZE = DatabaseDescriptor.getCommitLogSegmentSize() The MAX_MUTATION_SIZE equals the commitlog segment size Note: commitlog_segment_size_in_mb = 32 (by default). Also, commitlog_segment_size_in_mb*1024*1024 is the commit log segment size in bytes (Hope this helps and if anything is wrong please correct) > document commitlog segment size's relationship to max write size > ---------------------------------------------------------------- > > Key: CASSANDRA-10256 > URL: https://issues.apache.org/jira/browse/CASSANDRA-10256 > Project: Cassandra > Issue Type: Improvement > Components: Config > Reporter: Chris Burroughs > Priority: Trivial > Labels: lhf > > This is in the code: > https://github.com/apache/cassandra/blob/cassandra-2.1/src/java/org/apache/cassandra/db/commitlog/CommitLog.java#L57 > But not part of the description in cassandra.yaml -- This message was sent by Atlassian JIRA (v6.3.4#6332)
