Why listen to this podcast:

- The Compass backend is mostly written in Java and Python, with Go increasingly a first class language. The main reason for Go being added was developer productivity.

- The app is based on a Microservices architecture with around 40-50 services in total.

- Binary RPC, originally Thrift and Finagle, is used as the communication protocol, but the company is gradually moving to gRPC still with Thrift. One advantage that gRPC offers is better Python support than Finagle.

- The company has built a code generation framework which takes Thrift and converts it to a RESTful API for clients to consume.

- Constraint theory is about how you manage the one constraint in a system or team that prevent you increasing throughput; for example if your software engineering team only has one front end engineer do you ask back-end engineers to pick off some front-end tasks, or bring in a contractor.
