------------------------------------------
Summary: Waiting for sync on the commit log could happen after
writing to memtable
Key: CASSANDRA-7915
URL: https://issues.apache.org/jira/browse/CASSANDRA-7915
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Branimir Lambov
Priority: Minor
Currently the sync wait is part of CommitLog.add, which is executed in whole
before any memtable write. The time for executing the latter is thus added on
top of the time for file sync, which seems unnecessary.
Moving the wait to a call at the end of Keystore.apply should hide the memtable
write time and may improve performance, especially for the batch sync strategy.
