Subject [jira] [Updated] (BEAM-5074) Make BeamSqlRowComparator more general
Date Tue, 07 Aug 2018 19:27:00 GMT

     [ https://issues.apache.org/jira/browse/BEAM-5074?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Rui Wang updated BEAM-5074:
---------------------------
    Description: 
BeamSqlRowComparator returns reversed comparison results (if a < b in terms of value, BeamSqlRowComparator
returns a > b). 

 

Make it return forward results and have a reversed comparator to do the current thing.

 

  was:
BeamSqlRowComparator returns reversed comparison results (if a < b in terms of value, BeamSqlRowComparator
returns a > b). 

 

Add a flag to turn on/off this reversed effect. The reason of doing this is to help implement
ORDER BY ASC/DESC in the normal way.
