--------------------------------------
Summary: Avoid allocating unnecessary tag iterators
Key: HBASE-11774
URL: https://issues.apache.org/jira/browse/HBASE-11774
Project: HBase
Issue Type: Improvement
Reporter: Andrew Purtell
Assignee: Andrew Purtell
Priority: Minor
Fix For: 0.99.0, 2.0.0, 0.98.6
We can avoid an unnecessary object allocation, sometimes in hot code paths, by
not creating a tag iterator if the cell's tag area is of length zero,
signifying no tags present.
