Google Cloud PubSub

Google Cloud PubSub source plugin

Google Cloud PubSub is a fully managed messaging service provided by Google Cloud Platform that enables the exchange of messages between applications and services. It is designed to provide a scalable and flexible messaging solution for modern cloud-based architectures. One of the key benefits of PubSub is its scalability and flexibility. It can handle millions of messages per second and can scale up or down automatically based on the volume of messages being processed, making it an ideal candidate for your telemetry data.

You can use the Google Cloud PubSub source plugin to configure your Calyptia Core pipeline to collect data from your Google Cloud PubSub instances.
