Description Michael Stead 2016-01-21 13:51:54 UTC

Description of problem:

Developer consumer auto-attach is taking a long time (1 - 2 minutes) on some deployments.


Version-Release number of selected component (if applicable):
0.9.51.14

How reproducible:
100%

Steps to Reproduce:
1. Register (+ auto-attach) a development consumer against a candlepin instance that has a very large number of pools (stage).

sudo subscription-manager register --user YOUR_USER --password YOUR_PASS --auto-attach

Actual results:
Registration + auto-attach can take quite some time to complete.

Expected results:
Should not take this long to register and auto-attach a dev entitlement.

Additional info:

This bug is directly related to the number of pools that exist on a candlepin instance and appears to be related to the query that checks for an existing dev pool associated with a consumer on auto-attach.

Comment 1 Michael Stead 2016-01-21 13:54:45 UTC

It is important to note that this bug is not applicable to an auto-attach with a standard consumer, and is only seen when auto-attaching with a dev consumer.

Comment 2 Michael Stead 2016-01-25 17:24:42 UTC

Updated the query to filter pools by the consumer's owner.

Total time for registration + auto-attach for developer consumer now at around 18s.

Comment 3 Tramaine Darby 2016-01-26 14:52:31 UTC

Fix deployed to production on 1/25/2016 - 0.9.51.15

Comment 4 Barnaby Court 2016-07-22 14:39:33 UTC

Moving to closed per the updated candlepin process for bugs that have been merged or have been taken care of.
