Hedwig is a inter-service communication bus that works on AWS and GCP, while keeping things pretty simple and straight forward. It uses json schema draft v4 for schema validation so all incoming and outgoing messages are validated against pre-defined schema.
Hedwig allows separation of concerns between consumers and publishers so your services are loosely coupled, and the contract is enforced by the schema validation. Hedwig may also be used to build asynchronous APIs.
Support exists for Python and Golang.
For intra-service messaging, see Taskhawk.
Add to Cargo.toml:
toml
[dependencies]
hedwig = "1"
To use the Google Publisher, enable the google feature as well:
toml
[dependencies]
hedwig = { version = "1", features = ["google"] }
See the examples in the repository as well as the crate-level documentation for usage examples.
We use GitHub issues for tracking bugs and feature requests.
