Two presentations on MongoDB, one given by Dwight Merriman, 10gen CEO, at NYC MySQL Group at Sun and the other by Mike Dirolf (@mdirolf) at Codemash 188.8.131.52.
Two quick notes about the slides:
I really like the overview of the database world
and the scalability/performance vs depth of functionality graphic:
I am a bit confused by MongoDB’s placement on the CP axis
As far as I know, MongoDB doesn’t use 2PC or a Paxos implementation for ensuring consistency, so I was tempted to place MongoDB more on the A+P axis. But maybe I am just misinterpreting the slide (nb the corresponding presentation fragment doesn’t really clarify it either)
