Episode description
gRPC (gRPC Remote Procedure Calls[1]) is an open source remote procedure call (RPC) system initially developed at Google in 2015[2]. It uses HTTP/2 for transport, Protocol Buffers as the message format.
In this video I want to explore gRPC, go through examples, pros and cons of gRPC.

gRPC Pros and Cons
Pros
- Fast two/uni and request
- Unform
- One library to rule them all
- Progress feedback( long synchronous requests) drop pluggable wait...)
- cancel request
- All benefits of H2 and Protobuff
Cons
- schema based (not everyone wants schema)
- Thick client - limited languages - Proxies still don’t understand it
- Still young
- Error handling
- No native browser support
- Timeouts, circuit breaker just like any RPC (pub/sub rules in this case)
Can you create your own protocol?
