Karan Mehta created PHOENIX-4950:
------------------------------------
Summary: SYSTEM.STATS table should include the stopKey of guide
posts
Key: PHOENIX-4950
URL: https://issues.apache.org/jira/browse/PHOENIX-4950
Project: Phoenix
Issue Type: Improvement
Reporter: Karan Mehta
SYSTEM.STATS table should include stop key for each guidepost along with start
key. This helps in determining if there are any gaps/holes in the statistics.
UPDATE STATISTICS creates separate scanners for each region and runs it in
parallel. This can potentially fail if particular region is unavailable or
SYSTEM.STATS is unable when the region tries to commit stats. This Jira will
help increase overall resiliency of stats feature. This concept is similar to
how hbck determines holes in the chain.
Kudos to [~sukumaddineni] for the idea!
