Subject [jira] [Created] (PHOENIX-4807) Document query behavior when statistics unavailable for some table regions.
Date Tue, 10 Jul 2018 17:50:00 GMT
Guru Prateek Pinnadhari created PHOENIX-4807:
------------------------------------------------

             Summary: Document query behavior when statistics unavailable for some table regions.
                 Key: PHOENIX-4807
                 URL: https://issues.apache.org/jira/browse/PHOENIX-4807
             Project: Phoenix
          Issue Type: Task
            Reporter: Guru Prateek Pinnadhari


When troubleshooting an issue with retrieval of duplicate records for a select query on same
PK, the behavior seen was: query plan's collection of Scan objects were such that they led
to generation of overlapping scans on a salted table's regions.

A contributing factor was statistics being unavailable for the terminal regions of the table.
Filing Jira to add a note about this on [https://phoenix.apache.org/update_statistics.html]
