SUMMARY

Re-do the pull request here:

ansible/ansible-runner#269

Make all tests in ansible-runner pass, verify functionality with AWX, and hand over to be performance tested.

[AlanCoding]

I'm putting blocked label on, because I would like to hold off until we get a disposition on ansible/ansible-runner#957

[shanemcd]

@AlanCoding Can this move out of Blocked now?

[AlanCoding]

Yes, agreed, moved.

[AlanCoding]

This should be a performance improvement on execution nodes, similar in scope to the performance improvement we get for controller nodes from #11356

@jbradberry @rebeccahhh Do you have capacity to handle this in this iteration?

[jbradberry]

@ikhan2010 probably

[rebeccahhh]

I do

[ikhan2010]

@rebeccahhh thanks for stepping up. Kindly let me know how much effort is this.

[rebeccahhh]

I am on PTO for a week so @jbradberry if you want to get progress on this don't wait for me (no pressure, I'll be back after PyCon).

[AlanCoding]

I'm going to put this in Unplanned for now (because planning is starting and it will be at home with other perf/scale issues). Please put it back into In Progress if you pick it back up again @rebeccahhh

[rebeccahhh]

I put a draft PR up last week but I am working on other things so this is kind of on my back burner: ansible/ansible-runner#1072
