- 3. gRPC: Microservices at Square Manik Surtani Senior Infrastructure Engineer, Square @maniksurtani
- 4. We <3 JSON/HTTP
- 5. We also <3 monoliths* (*) Not really. http://squ.re/spot
- 6. We preferred microservices
- 7. Java Go Ruby
- 8. Java Go Ruby x 500
- 9. Stubby and Sake ● JSON/HTTP for mobile & web client comms ● Replace server comms with Sake ● Stubby DNA ● Implements protobuf services ○ proto2
- 10. Sake Often better warm ● Java ○ Asynchronous comms, blocking APIs ○ Deadline propagation ○ ACLs ○ Integrates with service discovery ○ Distributed tracing ○ Retry logic ● Ported to Go ● Ruby support via a sidecar ○ Based on the Java impl
- 11. Modernizing Sake ● Move networking to Netty ● Open source Sake! ● Move to HTTP/2 ○ Streaming! ● Native Ruby implementations ○ No more sidecars
- 12. ARCWire ● A Google effort ● A proto service based RPC framework ● Stubby DNA ● HTTP/2 ● Open Source
- 13. gRPC Features ● Request/response as well as bidirectional streams ● Synchronous and asynchronous ● Backed by non-blocking IO ● Header compression ● Multiplexing requests over a single connection ● Built with mobile clients in mind ○ Better battery life, data usage than JSON/HTTP
- 14. Supported Platforms Java (inc. Android) Python Go PHP C Ruby C++ Node.js Objective-C C#
- 15. Message format ● Built for protocol buffers * ● Pluggable ● Other serialization formats could be used instead ○ Avro, Thrift, Cap’n Proto, etc. * http://developers.google.com/protocol-buffers
- 16. Protocol buffers ● Language-neutral, platform-neutral ● Extensible ● Binary, very compact ● Strongly typed ● Versioned ● Easily transformed to JSON for debugging
- 17. Protocol Buffers
- 18. Protocol Buffer Services
- 19. Protocol Buffers
- 20. gRPC Server
- 21. gRPC Server
- 22. gRPC Client
- 23. Adding gRPC to your stack ● Protobuf version control ● Service discovery ● Load balancing ● Security ● Logging ● Metrics
- 24. gRPC performance ● Measured by etcd * ● 120µs round trips, compared to 1.6ms roundtrips for JSON/HTTP ● 3 orders of magnitude?! * http://bit.ly/etcd_grpc
