-------------------------------------------
Summary: Drop commitlog chain marker updates
Key: CASSANDRA-18894
URL: https://issues.apache.org/jira/browse/CASSANDRA-18894
Project: Cassandra
Issue Type: Improvement
Components: Local/Commit Log
Reporter: Branimir Lambov
CASSANDRA-13987 added a periodic update of the last commit log chain marker in
order to allow for data in memory-mapped segments to be recovered even if it
was not part of a synced segment.
A much simpler way to do this is something in the vein of CASSANDRA-16482, i.e.
ignoring an empty sync marker for the last entry in the commit log. We could do
this by default if the commit log is uncompressed (and possibly only if using
memory mapping after CASSANDRA-18464).
