Tak-Lon (Stephen) Wu updated HBASE-28055: ----------------------------------------- Fix Version/s: 2.6.0 2.4.18 2.5.6 3.0.0-beta-1 4.0.0-alpha-1 > 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: 3.0.0-alpha-4, 2.5.5 > Reporter: Sergey Soldatov > Assignee: Sergey Soldatov > Priority: Major > Fix For: 2.6.0, 2.4.18, 2.5.6, 3.0.0-beta-1, 4.0.0-alpha-1 > > > 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. -- This message was sent by Atlassian Jira (v8.20.10#820010)
