Hi,
Another database option that works well with Python is MongoDB, although it is
NoSQL rather than SQL type.
For an example of the use of MongoDB with Python and Ryu, check out the nmeta
reactive SDN project at https://github.com/mattjhayes/nmeta
I suspect however that the answer that Arslan needs is to either write a
program in Python and run it with ryu-manager, as per the tutorial at
http://ryu.readthedocs.io/en/latest/writing_ryu_app.html, or interface using
the REST API.
Regards,
Matt.

controller application?
Hi Arslan,
The features for connecting to Databases, MySQL(as you said), PostogreSQL and
SQLite for example,
are out of scope of Ryu SDN framework, I guess.
On the other word, Ryu user can use their own favorite libraries, frameworks or
ORM (Object
Relational Mapper) for connecting to Databases.
FYI, for getting started with Databases using Python, I recommend you to use
ORMs.
Django Models(a part of Django web framework) seems to be most famous in
Python, but SQLAlchemy
is adopted to OpenStack (also Ryu is using SQLAlchemy to implement optional
feature).
How about trying them?

method of associating user-defined Python classes with database tables, and
instances ...
