I see there is 'projections' in Project Ideas I think it would be a great thing to have...so I just wanted to add my +1000 to the idea [😃] [😶]
EventStore will have them soon in v4.0.0 http://docs.geteventstore.com/introduction/3.9.0/projections/ DL seems great at scaling... so with projections it would make a great store for event sourcing
