I'll be around here to answer any questions about fiesta. Any feedback would be greatly appreciated!

Thanks! Glad to hear that the effort is appreciated :). We all try pretty hard to make sure everyone has a good experience with MongoDB.

Have you checked out this page: http://www.mongodb.org/display/DOCS/Schema+Design

I think there are also some videos linked from there that should help.

MongoDB does not currently have single-server durability, so a crash can cause loss of data. As you point out, replication is the recommended path to durability. We'll also probably be adding support for single-server durability by 1.8.

That said, the article seems to imply "missing documents" with no crash. That is something I've never seen reported before this post.

Tried to comment on the post, but so far still "Awaiting Moderation". I have never heard reports of missing documents w/ a production release of MongoDB (or a dev release, for that matter). Would love to help debug whatever issue he saw, but will need more info than that post gives.

just a note for people who come across this and are confused: queries in MongoDB use a much more concise document-based query language, not map/reduce. map/reduce in MongoDB is just for aggregations / ETL type operations

This is fixed now - large deletes won't block the world forever: http://jira.mongodb.org/browse/SERVER-494
