Episode 134 - gRPC

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?
