Module Description

This module implements XEP-0049: Private XML Storage, allowing users to store custom XML data in the server's database. Used e.g. for storing roster groups separator.


  • iqdisc (default: one_queue)
  • backend (atom, default: mnesia): Storage backend. Currently mnesia, odbc, riak and mysql are supported . mysql uses MySQL-specific queries so in some cases it is more efficient than generic odbc.

CAUTION: Riak KV backend doesn't support transactions (rollbacks), so please avoid inserting more than one value in one set request, otherwise you may end up with partially save data, backend returns first error.

Example Configuration

{mod_private, []}
