Subject [jira] [Created] (PHOENIX-3907) Use LATEST_TIMESTAMP when UPDATE_CACHE_FREQUENCY is not zero
Date Fri, 02 Jun 2017 18:17:04 GMT
James Taylor created PHOENIX-3907:
-------------------------------------

             Summary: Use LATEST_TIMESTAMP when UPDATE_CACHE_FREQUENCY is not zero
                 Key: PHOENIX-3907
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3907
             Project: Phoenix
          Issue Type: Bug
            Reporter: James Taylor


Currently with UPDATE_CACHE_FREQUENCY, we'll use LATEST_TIMESTAMP *most* of the time, until
the cached entity expires, in which case we'll use the server timestamp. This seems a bit
strange and inconsistent. We should instead always use LATEST_TIMESTAMP if UPDATE_CACHE_FREQUENCY
is non zero, with the exception of the corner case for UPSERT SELECT and DELETE where the
same table is being read and written to (see changes to FromCompiler for PHOENIX-3823).
