One of our clients is talking about moving to Mongo for their reporting/data mart. I suspect the real issue is the architecture of their data mart schema, however I don't want to start pushing back if I can't back it up.
Anyone have any thoughts on why we would / would not use Mongo for a reporting environment.
what are the use cases where mongo is a good fit? what are the drawbacks long term? is mongo a persistent db or simply a big memory cache? does mongo have advantages over Postgres hstore? etc...
