Subject: [PATCH 678/678] extras/group : add database workload profile
|
|
|
7c2869 |
|
|
|
7c2869 |
Running DB workload patterns with all perf xlators enabled as default has
|
|
|
7c2869 |
resulted into some inconsistency issues. Based on the internal testing done by
|
|
|
7c2869 |
Elko Kuric (ekuric@redhat.com) there're certain set of perf xlators which need
|
|
|
7c2869 |
to be turned off to get these types of workload supported by Gluster.
|
|
|
7c2869 |
|
|
|
7c2869 |
The proposal is to leverage group profile infrastructure to group together all
|
|
|
7c2869 |
those tunables at one place so that users just need to apply the profile to the
|
|
|
7c2869 |
volume to use it for the data base workload.
