Use mongodb as database for ejabberd

Hello,

I'm already using Mongodb in my web application and I installed ejabberd to offer a chat service. The problem is I don't want to use a MySQL database because I would duplicate a lot of data.

I have been searching a little and I found some ODBC drivers for mongodb:

http://www.progress.com/products/datadirect-connect/odbc-drivers/data-so... -> not free

http://www.simba.com/connectors/mongodb-odbc -> it looks quite good, but you also have to pay.

mongoDb ODBC Driver - https://github.com/NYUITP/sp13_10g - free, but it's in beta.

Also I found that you could use a ODBC compatible database in the ejabberd documentation:

http://svn.process-one.net/ejabberd/tags/ejabberd-2.0.5/doc/guide.html#odbc

I would like to know if it is possible to connect ejabberd to mongodb using the mongo ODBC driver.

Has anyone tried something similar? Could you provide some information?

Thanks in advance
