Subject [jira] [Commented] (CLOUDSTACK-9340) General DB Optimization
Date Fri, 08 Apr 2016 13:53:25 GMT


ASF GitHub Bot commented on CLOUDSTACK-9340:

Github user rafaelweingartner commented on the pull request:
    it is complain about a column called "size" at the "schema-40to410.sql"
    > schema-40to410.sql: Duplicate column name 'size'
    That is a little weird because you did not change anything there. It is looking like an
environment problem. Maybe with a little luck and a push -f, the Jenkins job is executed somewhere
else and that problem goes away?

> In some production environments there were being experimented delays in most of the jobs.
A search for DB optimization was taken and some deficiencies were discovered, we can group
them in 4 groups:
> * Incorrect PRIMARY key
> * Duplicate PRIMARY KEY
> * Missing indexes (Add indexes to avoid full table scans)
> * Some views query (Change view to improve account retrieval speed)
