Summary: Granular segment lock for SegmentedRaftLog
Key: RATIS-2390
URL: https://issues.apache.org/jira/browse/RATIS-2390
Project: Ratis
Issue Type: Improvement
Reporter: Ivan Andika
Currently, SegmentedRaftLog uses RaftLogBase.lock for all its operations even
those that only operates on certain segments (e.g. purge, appends). It might be
possible to reduce contention by having a unique lock per segment.
For example, operations that need to operate on segments only need to hold read
lock on RaftLogBase.lock and subsequently try to hold SegmentedRaftLog segment
locks. We can implement something like writeLock(TermIndex fromIndex, TermIndex
toIndex) and SegmentedRaftLog should only pick the segments locks for that
range.
