• Go-CQRS-EventSourcing-Microservice

  1 86 0.0 Go

  Go-CQRS-EventSourcing-Microservice

Source code you can find in GitHub repository. The main idea of this project is the implementation of Event Sourcing and CQRS using Go, Postgresql, Kafka for event store and Mongo, ElasticSearch for read projections. Previously have written same articles where implemented the same microservice using Go and EventStoreDB, and Spring, as written before, repeat, think EventStoreDB is the best choice for event sourcing, but in real life at some projects we usually have business restrictions and for example usage of the EventStoreDB can be not allowed, in this case, think postgres and kafka is good alternative for implementing our own event store. If you don't familiar with EventSourcing and CQRS patterns, the best place to read is microservices.io, blog and documentation of eventstore site is very good too, and highly recommend Alexey Zimarev "Hands-on Domain-Driven Design with .NET Core" book.

• validator

  68 15,562 7.4 Go

  :100:Go Struct and Field validation, including Cross Field, Cross Struct, Map, Slice and Array diving

  

Our microservice accepts HTTP and gRPC requests: The bank account REST controller, which accept requests, validate it using validator, then call a command or query service. The main reason for CQRS gaining popularity is the ability to handle reads and writes separately due to severe differences in optimization techniques for those much more distinct operations. As Go http framework used echo.

  Discontinued Former GUI client for gRPC services. No longer maintained.

  

Can recommend bloomrpc is good GUI Client for GRPC Services. Grpc service handlers:
