[Bug 1404076] Re: Optimize Ceilometer resource list query

[Chris J Arges]

Hello Rohit, or anyone else affected,

Accepted ceilometer into trusty-proposed. The package will build now and
be available at
https://launchpad.net/ubuntu/+source/ceilometer/2014.1.5-0ubuntu2 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

  Optimize Ceilometer resource list query

Status in Ceilometer:
  Fix Released
Status in ceilometer package in Ubuntu:
  Fix Released
Status in ceilometer source package in Trusty:
  Fix Committed

Bug description:
  [Impact]

   * Ceilometer resource-list requires an open-ended scan of resource
  and sample tables to retrieve a unique list of resources.  There
  should be a way to optimize the scans.

  [Test Case]

   * Deploy an openstack cloud using the current trusty package of ceilometer.
   * Run a 'ceilometer resource-list' without the patch the running
  time for that command takes (if returns).

  ubuntu at queen:~$ time ceilometer resource-list | wc -l 
  10031 real	1m3.975s user	0m3.572s sys	0m0.187s 
  ubuntu at queen:~$ time ceilometer resource-list | wc -l 
  10036 real	1m54.993s user	0m3.354s sys	0m0.184s 

  * With the included SRU patch :

  real	0m15.693s
  user	0m1.104s

  sys	0m0.065s
  [Regression Potential] 

   * None expected.

  [Other Info]

  * Backport of https://review.openstack.org/142951
