James Taylor reassigned PHOENIX-4674: ------------------------------------- Assignee: Abhishek Singh Chouhan > Incorrect stats if data size is less than guidepost width > --------------------------------------------------------- > > Key: PHOENIX-4674 > URL: https://issues.apache.org/jira/browse/PHOENIX-4674 > Project: Phoenix > Issue Type: Bug > Reporter: Abhishek Singh Chouhan > Assignee: Abhishek Singh Chouhan > Priority: Major > > For a small table, lets say with a single region < guidepost width, the stats > after running update statistics can be way off. This is because we get an > empty guidepost for the region and in BaseResultIterators we end up > estimating the #rows as guidepostwidth/estimated row size of the table. For a > table having <100 rows and guidepost width size of 100 mb, if the estimated > row size is 100 bytes we end up estimating a million rows. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
