mongodb inMemory engine available in the community edition? I'm currently working with MongoDB 3.2.10 and I recently heard of the new "inMemory" engine. After some research I found that it was available in the Enterprise Edition since version 3.2.6, but I couldn't find any information on an eventual release in the community edition. 

So the question is: do they plan to release the inMemory engine for the Community Edition? If they do, do we know when?
As at MongoDB 3.4, no plans have been announced to make the In Memory Storage Engine available in the MongoDB Community Edition. I suspect this is likely to remain as an Enterprise-only feature for the foreseeable future given the more niche use cases for in-memory storage, however the definitive source will be the mongodb.com website and any future major release announcements.

FYI, you can subscribe to driver/server release announcements via the mongodb-announce group.
