Criteo is still an active user of Mesos, running it worldwide for most of its 
production workloads.

We currently run a fork of Mesos 1.9.x (with some patches that were not 
upstreamed but not that much), and we don't plan to upgrade to the latest 
version for now.

We will continue to propose patches regularly upstream when possible, but can't 
really commit on actively contributing on particular needs in Mesos ecosystem.

Also if you are still a user of mesos, please chime in.
Qian, it might be worth having a more explicit email asking users to chime in 
as this email was tailored more for contributors.

Twitter is still using mesos heavily, we upgraded from a branch based off of 
1.2.x to 1.9.x in 2021, but haven't upgraded to 1.11.x yet. We do have a lot of 
patches carried on our branch that have not been upstreamed. I would like to 
upstream them to avoid relying on many custom patches and to get closer to 
HEAD, but it will take time and quite a bit of work, and it's not a priority at 
the moment.

On the contribution side, at this point if I were to continue contributing, it 
would be on a volunteer basis, and I can't guarantee having enough time to do

Hi all,

I'd like to restart the discussion around the future of the Mesos project. As 
you may already be aware, the Mesos community has been inactive for the last 
few years, there were only 3 contributors last year, that's obviously not 
enough to keep the project moving forward. I think we need at least 3 active 
committers/PMC members and some active contributors to keep the project alive, 
or we may have to move it to 

Call for action: If you are the current committer/PMC member and still have the 
capacity to maintain the project, or if you are willing to actively contribute 
to the project as a contributor, please reply to this email, thanks!
