Pub/Sub
The pubsub package provides an easy and portable way to interact with
publish/subscribe systems. This guide shows how to work with pubsub
in the Go CDK.
The publish/subscribe model allows parts of a system to publish messages that other parts of a system may subscribe to. This is commonly used to arrange for work to happen at some point after an interactive frontend request is finished or in other event-driven computing.
The pubsub package supports operations to publish messages to a topic and
to subscribe to receive messages from a topic.
Subpackages contain driver implementations of pubsub for various services,
including Cloud and on-prem solutions. You can develop your application
locally using mempubsub, then deploy it to multiple Cloud providers with
minimal initialization reconfiguration.
