Investigate memory issues with mongoengine 0.13+
Description
Even just restarting Pulp services with mongoengine 0.13 results in noticeable (400-700MB) increase of memory consumption in comparison to older versions of mongoengine. Investigation needed.
0.13 is not in Fedora yet, Fedora 27 currently contains python-mongoengine 0.12.
https://apps.fedoraproject.org/packages/python-mongoengine/overview/
The outcome of this task depends on the investigation results but I expect it to be one of the following:
- either mongoengine version restriction
- or note in docs that 0.13 consumes more memory
- or fix to the Pulp code if high memory consumption is caused by a certain use case which we can change in a backward compatible way to continue support of older mongoengine versions.
Upd: I think it is worth testing the most recent mongoengine, though I do not see 0.14 on PyPI at the moment.
https://github.com/MongoEngine/mongoengine/releases/tag/v0.14.0
Just a small note that 0.14 is already out, that means, 0.13 will not get into Fedora

i went through this and i think this it is ready to be marked as groomed.
I want to share two thoughts about this issue.
- While this is regretable I think practically it will only impact a Pulp running on a future version of Fedora. With that limited impact I think not fixing this bug would be OK.
- If this is investigated, I think we need to understand if Pulp is doing something wrong or if its a mongoengine regression. Has this bug been filed with upstream mongoengine? Maybe we could reduce Pulp's usage of mongoengine to a simpler reproducer that proves Pulp isn't creating the problem (or that it is).
- Groomed changed from No to Yes
- Status changed from NEW to CLOSED - WONTFIX
