Summary: Short-circuit comparison of rows in CellComparator
Key: HBASE-14524
URL: https://issues.apache.org/jira/browse/HBASE-14524
Project: HBase
Issue Type: Improvement
Reporter: Lars Francke
Assignee: Lars Francke
Priority: Minor
{{CellComparator#compareRows}} compares two rows. For Scans and Gets these
objects can sometimes be exactly the same object.
I see this (without fully understanding all everything that's going on) for the
first cell in each row.
In these circumstances I think it makes sense to short-circuit the comparison
(not do a byte comparison and class cast checks) and bail out early if the
objects are identical.
