Question

Short Question:
Is there any nosql flat-file database available as sqlite?

Explanation:
Flat file database can be opened in different processes to read, and keep one process to write. I think its perfect for read cache if there’s no strict consistent needed. Say 1-2 secs write to the file or even memory block and the readers get updated data after that.

So I almost choose to use sqlite, as my python server read cache. But there’s still one problem. I don’t like to rewrite sqls again in another place and construct another copy of my data tables in sqlite just as the same as I did in PostgreSql which used as back-end database.

so is there any other choice?thanks!

Maybe shelve? It’s basically a key-value store where you can store python objects. http://docs.python.org/library/shelve.html

Or maybe you could just use the filesystem?
