  1. XA Support

    Is there any plan to implement distributed transaction that involves more than one data stores (for e.g. an RDBMS and Mongo)? We have one such requirement and tried a simple POC by creating a simple class extending XAResource (MongoXAResource implements XAResource) and overriding below methods.

    @Override
    public void commit(Xid xid, boolean b) throws XAException {
    clientSession.commitTransaction();
    }

    @Override
    public void rollback(Xid xid) throws XAException {
    clientSession.abortTransaction();
    }

    It appears to work but i think there is a lot more to do. Is there any plan to implement by MongoDB team?
