What challenges/issues did Instagram and Pinterest face when using Django to build social networking sites?
Did they make any changes to Django to overcome these challenges?
Yes, both Instagram and Pinterest made modifications to Django to better suit their needs. For example, Instagram created an entirely new framework, called Django-Nonrel, that allowed them to use a NoSQL database instead of SQL. Pinterest also made significant changes to how they stored and retrieved data to improve performance.
