Description Liran Zelkha 2013-07-16 13:39:51 UTC
Description of problem:
When AutoRecoveryManager runs it generates a query to select all VDS with a specific group name. This query is slow and can be optimized easily.

Version-Release number of selected component (if applicable):


How reproducible:
Run engine.

Steps to Reproduce:
1. Connect with a profiler to engine, and examine queries.
2.
3.

Actual results:
Generated query is:
SELECT * FROM (SELECT * FROM vds WHERE ( vds_id IN (SELECT vds_with_tags.vds_id FROM  vds_with_tags   WHERE  vds_with_tags.vds_group_name LIKE 'Default' ))  ORDER BY vds_name ASC ,vds_name ASC ) as T1 OFFSET (1 -1) LIMIT 2147483647

Expected results:
Should be SELECT * FROM vds WHERE vds_group_name LIKE 'Default' ORDER BY vds_name ASC as T1 OFFSET (1 -1) LIMIT 2147483647
