Lars Hofhansl commented on HBASE-9769: -------------------------------------- Lastly (and sorry for being difficult), why is this faster than passing the small row hint to ExplicitColumnTracker and replace SEEK_NEXT_COL with SKIP? (this would be HBASE-9778 but with your explicit hint) It seems the ExplicitColumnTracker then does close to the same work as ScanWildcardColumnTracker. > Improve performance of a Scanner with explicit column list when rows are > small/medium size > ------------------------------------------------------------------------------------------ > > Key: HBASE-9769 > URL: https://issues.apache.org/jira/browse/HBASE-9769 > Project: HBase > Issue Type: Improvement > Components: Scanners > Affects Versions: 0.98.0, 0.94.12, 0.96.0 > Reporter: Vladimir Rodionov > Assignee: Vladimir Rodionov > Attachments: 9769-0.94-sample1.txt, 9769-0.94-sample2.txt, > 9769-0.94-sample.txt, 9769-94.txt, 9769-94-v2.txt, 9769-trunk-v1.txt, > 9769-trunk-v2.txt, 9769-trunk-v3.txt, 9769-trunk-v4.txt > > -- This message was sent by Atlassian JIRA (v6.1#6144)
