In order to deal massive (Big) data in one of my applications. I am testing MySQL with MariaDB and TokuDB. Previously I had used PostgreSQL for my applications but the Reporting Engine I am designing requires some unique features to update data faster and retrieve it in an efficient manner. TokuDB being based on Fractal Indexing makes the insertion faster for Bigger Data and keeps the database compressed resulting in efficient use of storage data. While running MySQL MariaDB with Django in my virtual environment, I encountered following error:
django.core.exceptions.improperlyconfigured error loading mysqldb module no module named mysqldbFull Trace is:

Use following command:
pip install mysql-pythonand if you are not using virtualenv, then use:
sudo pip install mysql-python
