Hi,

If you recall, we asked a custom question during the user survey, and
the preliminary results are there, thanks to Heidi.

I've compiled them and here's what it boils down to on 93 answers made
of 138 choices:

- Legacy MongoDB: 56 (60.2% of users, 40.5% of choices)
- Gnocchi: 44 (47.3% of users, 31.8 % of choices)
- HTTP: 8 (8.6% of users, 5.8% of choices)
- Legacy MySQL: 8 (8.6% of users, 5.8% of choices)
- Other: 8 (8.6% of users, 5.8% of choices)
- File dispatcher: 7 (7.5% of users, 5% of choices)
- Kafka: 4 (4.3% of users, 2.9% of choices)
- Legacy PostgreSQL: 3 (3.2% of users, 2.1% of choices)


Note that:
- some of the "Others" are actually "Kafka"
- the percentage overs users not sum to 100% since some people checked
  several choices, I also included the percent over the number of
  choices which sums up to 100%

It _seems_ to me that everyone is starting to move away from MongoDB to
Gnocchi slowly but surely. Hurrah?

We only run the notification agent to republish notifications from RMQ to Kafka
would like to use gnocchi but it isn't stable in this version. looking forward to it being fixed in the next version.
