I checked it, too. The reason why python client raises error is it
expects driver has dict parameter in config field. But the doctor driver
has None in the field, then it causes "'NoneType' object has no
attribute 'items'".
The workaround I think is python client will allow None in the config
field, or another is Congress Server returns {} if the field is None. I
pushed a patch about first workaround[1], so please check it.

I tried the doctorDriver again. This time I was successful! I'm still
getting an error when listing the datasources though. I tried updating

I tried the doctor driver out. I just added the file to
congress/datasources, and set up /etc/congress/congress.conf to
include congress.datasources.doctor_driver.DoctorDriver.
I could create a new doctor driver, but afterwards I couldn't list
all the datasources, and I couldn't push any data to it. See
transcript below.

The other problem I saw was that the schema was fixed for the doctor
driver. So I tried to create a push driver that would accept any
collection of tuples. This wouldn't allow the user to push
arbitrary JSON, but they could push any tuples they'd like. While
experimenting, I fixed the problem mentioned above by adding a
single (unnecessary) configuration option. Then I ran into a
Datasource not found problem. I pushed the code to review so we can
all take a look.

Masahito: do you know what the Datasource Not Found problem is? If
not, could you look into it? I ran into it with the Doctor Driver too.

Hi folks,
This[1] is the driver I mentioned at meeting. It is used for OPNFV
Doctor[2]. So I plan to push it into master in Newton release, since
feature freeze for Mitaka was passed and the schema of its
translator is
under the discussion.
If it's worth to push it in current release to test push driver,
I don't
mind doing it.
