[Public] Hi,
CommitLog uses mmap (memory mapped ) segments by default. Direct-IO feature is proposed through new PR[1] to improve the CommitLog IO speed. Enabling this by default could be useful feature to address IO bottleneck seen during peak load. Need your input regarding changing this default. Please suggest. https://issues.apache.org/jira/browse/CASSANDRA-18464 thanks, Amit Pawar [1] - https://github.com/apache/cassandra/pull/2777
