Section 3: Internals Deep Dive

Why gRPC?

  • Efficiency serialization/deserialization over JSON

HTTP 1.0

  • opens a TCP connection for every request
  • plaintext headers (bigger latency for each call)

HTTP 2.0

  • one TCP connection
  • server push
  • multiplexing
  • headers/data compressed to binary
  • SSL connection required by default

Types of API

  1. Unary
  2. Server streaming
  3. Client streaming
  4. Bi-directional streaming
