Is Mongo good for transient storage (high volume of object creates & deletes)?

Question

I have an application that will periodically create a large number (10,000+) of hashes (collections of name/value pairs). The hashes may be manipulated a few times, and then deleted.

Is MongoDB an appropriate choice for this? Are there any obviously-better-suited alternatives?

Answer 1

Mongo is a document database and a bit overkill for key/value pairs. It's strength lies in that it can do ad hoc queries in the documents. If you need this, then that's great.

Take a look at tokyocabinet. This is rumored to be a very fast key/value store.
