---------------------------------------
Summary: Performance improvement for scan over several stores.
Key: HBASE-28055
URL: https://issues.apache.org/jira/browse/HBASE-28055
Project: HBase
Issue Type: Bug
Affects Versions: 2.5.5, 3.0.0-alpha-4
Reporter: Sergey Soldatov
Assignee: Sergey Soldatov
During the fix of HBASE-19863, an additional check for fake cells that trigger
reseek was added. It comes that this check produces unnecessary reseeks because
matcher.compareKeyForNextColumn should be used only with indexed keys. Later
[~larsh] suggested doing a simple check for OLD_TIMESTAMP and it looks like a
better solution.
