Maybe then using SQL would help ;)

I like to approach OSM projects in a result-oriented rather than technology-oriented fashion. I'm not prepared to try out MongoDB just because "it's no SQL"; but if someone could demonstrate that, for example, they can load the whole planet into MongoDB on a single machine in less than a day, effortlessly apply minutely updates and still have a quick answer to queries like "give me all relations that have members in this bounding box", then I'd be interested. Or, indeed, anything else where MongoDB outperforms that which I currently use.

Are there any known examples like that?

Probably my data model could inspire a discussion about simplifying data
models, too?

Your code does not seem to properly support UTF-8 (it assumes that keys and values cannot be longer than 256 bytes whereas a 256-character UTF-8 string can be over 1kb in size).

Bye
