Description John Matthews 2011-02-15 14:33:58 UTC

We want to improve the performance of updating yum package metadata. Currently we run "createrepo --update" and it processes all the packages to look for updates.  

We want to skip the processing of all packages and only update the specific packages we know have changed.

Intent is to leverage createrepo's functionality and invoke the minimum metadata updates we need for a small collection of changed packages.  If changes are needed to createrepo we will work with the yum developers and see if they will accept our patch.

Aligning to Sprint 22 as this is part of a story in Sprint 22

Comment 2 John Matthews 2011-04-11 14:27:55 UTC

Last round of investigation was on update of a rhel5 repo with ~7k packages.  Update ran in ~90 seconds.  Roughly 70 seconds was spent in compression of filelists.tgz and formation of sqlite metadata.

We didn't see a means of noticeably improving performance.  Moving this bug to CLOSED WONT_FIX.
