-----------------------------------------------
Summary: 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
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.
