----------------------------------------------
Summary: Remove ImmutableSegment#getKeyValueScanner
Key: HBASE-17291
URL: https://issues.apache.org/jira/browse/HBASE-17291
Project: HBase
Issue Type: Improvement
Components: Scanners
Affects Versions: 2.0.0
Reporter: ramkrishna.s.vasudevan
Assignee: ramkrishna.s.vasudevan
Fix For: 2.0.0
This is based on a discussion over [~anastas]'s patch. The MemstoreSnapshot
uses a KeyValueScanner which actually seems redundant considering we already
have a SegmentScanner. The idea is that the snapshot scanner should be a simple
iterator type of scanner but it lacks the capability to do the reference
counting on that segment that is now used in snapshot. With snapshot having
mulitple segments in the latest impl it is better we hold on to the segment by
doing ref counting.
