[sqlalchemy] Re: Support for CouchDB
Hello Guys, Thanks for the info, i did expect that to be the case! I can understand that the architecture is indeed very different. As an extension to my question then, which DBMS would you guys recommend for stability. We have a small embedded platform which has an unreliable power source. We're currently using SQLite which appears to work pretty well, is that something you would recommend? or is there something else even simpler and more robust?

[sqlalchemy] Re: Support for CouchDB
Roger Binns has incorporated support for CouchDB into apsw by using SQLite virtual tables. Although apsw cannot be used directly by SQLAlchemy (as it is not dbapi compliant), you can pass an apsw connection to pysqlite connect() and then use that connection as a SQLAlchemy engine. I did some minimal work on a thin DBAPI compatibility layer on top of apsw and the initial results were encouraging but I have not been able to allocate any further time to it. I am not far enough in to know if it is a great idea that will work or an incredibly dumb one that has no chance of working! So if you want to do some hacking about with create_engine(creator = lambda ...) then you may just be able to get couchdb up and running with SQLAlchemy via apsw. If you try it, let me know how you get on. pjjH On Aug 25, 11:16 am, Rawlins rob...@supporttime.com wrote: Hello Guys, Thanks for the info, i did expect that to be the case!

Anecdotally, a venerable old database like BerkleyDB might be the even simpler but still very solid kind of choice, or maybe Tokyo Cabinet.
