Read Replica: Project demonstrates how we can implement database routing in Django to route read requests to replicas using some algorithm (implemented Round Robin) and write requests to primary database. https://gitlab.com/tendulkaramey/db-routing

Caching: Project demonstrates how we can implement caching in Django using Redis so that we can serve some of repeat requests directly from cache and thus lowering the load on database. https://gitlab.com/tendulkaramey/cricket-tracker
