2. What is Protocol Buffers? • Data serialization mechanism • Like JSON or XML but smaller and faster • Strongly Typed Variables • Java, Python, Objective-C, Dart, Go, Ruby, and C# • Column index ◦ 1-15 → 1 byte ◦ 16 - 2047 → 2 byte ◦ 19000 - 19999 rezerve
3. Good for? • Fast communication • Structured Message Definitions • Backward Compatibility ◦ Can Add/Remove fields
4. A Silver Bullet? • Not human-readable and human-editable • Not recommended for larger datasets • Only meaningful with the proto file
5. LET’S SEE SOME BITS
6. GRPC • gRPC is a modern open source high performance RPC framework that can run in any environment. • Binary Serialization • HTTP/2 • Using Protobuf 3
7. Service Definition
8. Supported RPC Types • Unary RPC ◦ the client sends a single request and gets back a single response. • Server streaming RPC ◦ the server sends back a stream of responses after getting the client’s request message. • Client streaming RPC ◦ the client sends a stream of requests to the server instead of a single request. • Bidirectional streaming RPC ◦ the client and server can read and write in any order.
