AsyncAPI Event Gateway

The Event Gateway solution by excellence

⚠️ Still under development, it didn't reach v1.0.0 and therefore is not suitable for production use yet.

Overview

AsyncAPI Event Gateway (name is subject to change) is the Event Gateway solution by excellence.

Based on traditional API Gateways, it intercepts all incoming messages moving them into a pipeline of middlewares and handlers such as:

Message validation
Message manipulation
Message aggregation
Message filtering
Authentication
Throttling
Routing
Monitoring (including tracing)

It supports all the protocols AsyncAPI supports through bindings.

This Event Gateway is also compatible with the HTTP protocol, natively or through an external provider like Krakend.io.

Goals

1. Performance-first while ensuring message delivery

The Event Gateway it's a stateless solution that ensures messages are delivered as fast as possible using a minimal resource footprint. Delivering messages as a top priority means no data loss should happen.

2. Transparent usage.

No change in the user's code is needed. The service acts as a proxy between the client and the final broker(s). Messages infer the protocol based on the shape of the input network packet.

3. Fully configurable.

The service is entirely configurable, and the user can specify the settings for all protocols as well. For example, consumers' and producers' settings.

4. API-first

The service provides an API for uploading AsyncAPI specs, allowing the user to update their message validation, among others, very quickly. It could even be an automated task whenever you update your specs.

5. Extensible

The Event Gateway can extend its functionality via middlewares written by the community. A catalog of middlewares made by the community is also available.

Roadmap

The idea is to keep iterating and support all the protocols AsyncAPI supports through bindings.
However, we reduced the scope for the first versions, so we can give support to the most used protocols.

For the first version, only Kafka protocol will be supported.
