-------------------------------------
Summary: Re-enable reverse scan to prevent order by
Key: PHOENIX-1192
URL: https://issues.apache.org/jira/browse/PHOENIX-1192
Project: Phoenix
Issue Type: Bug
Affects Versions: 5.0.0, 4.1
Reporter: James Taylor
We have code in place and tested for usage of the reverse scan. It's just
turned off because the reverse scan ability never made it to 0.94. Now that we
have 4.x on top of 0.98, we should turn this back on. It's used to optimize
queries that do an ORDER BY in the descending order of the PK (to prevent the
standard and expensive order by processing). Prior tests have shown a dramatic
difference between the two ways of executing the query.
