It may be hype, but when MongoDB was released, what other RDBMS was offering the same functionality? I see Posgresql + JSON mentioned, but when was JSON support added?

I personally like MongoDB for: - flexible schema (less migration pain) - easy tags implementation - product attributes (list of name-value pairs) - GridFS - store binary files - nested documents for analytics (ex: a record for each day with a nested doc for each hour)

I wish MongoDB had - some support of join - multi-master replication

I personally used MongoDB as primary storage (yeay dot me), but currently prefer it as secondary storage.

As any product it evolves and I expect to see more improvements. I think MongoDB brought NoSQL to the masses :)

Just my 0.02. Thanks.

Everything you said is true, but I don't think the argument here is about the past, but rather about the future.

MongoDB was great and innovative compared to other solutions when it started, but now, it's dragged behind while other solutions are much better.

Then we should probably compare other NOSQL solutions to relational databases. Like CouchDb, CouchBase, FoundationDb, Neo4J, etc.
