Pub Sub

Pub Subs provide a common way to interact with different message bus implementations to achieve reliable, high-scale scenarios based on event-driven async communications, while allowing users to opt-in to advanced capabilities using defined metadata.

Currently supported pub-subs are:

• Redis Streams
• NATS

Implementing a new Pub Sub

A compliant pub sub needs to implement the following interface:

type PubSub interface {
	Init(metadata Metadata) error
	Publish(req *PublishRequest) error
	Subscribe(req SubscribeRequest, handler func(msg *NewMessage) error) error
}
