Would you happen to have any anecdotes of a project or dataset that MongoDB worked particularly well for you?
I'm working on a project where documents seem to work particularly well, though the core of the project is still in MySQL. I decided to give Mongo a shot for what I'm working on, but posts like this are a reminder to constantly be evaluating the technology you choose to use.
I use mongo for everything but the money (where cash is not involved) and for things not needing transactions. Have been sticking to MySQL for everything else (now moving to XtraDB).
For big big big projects and pure nosql I go with Cassandra (as long as you can feed it enough RAM). Otherwise, XtraDB can go the distance.
