Subject Re: [DISCUSS] Memory Mapped Journal Type

Hi Matt!

yes, it could be a good candidate for that purpose too and AFAIK are used in
MongoDb for the indexes!
Indeed the coolest thing is that if you disable data-sync on the broker
(choosing to be reliable only to process failures) you could experience
writes/reads with speed similar to those of plain memory access, with the
bonus of reducing the context switches due to the elimination of any
user-space->kernel-space interactions...
