Python Client for Pub/Sub Lite API

Pub/Sub Lite API : is designed to provide reliable, many-to-many, asynchronous messaging between applications. Publisher applications can send messages to a topic and other applications can subscribe to that topic to receive the messages. By decoupling senders and receivers, Google Cloud Pub/Sub allows developers to communicate between independently written applications.

Compared to Google Pub/Sub, Pub/Sub Lite provides partitioned zonal data storage with predefined capacity. Both products present a similar API, but Pub/Sub Lite has more usage caveats.

See the Google Pub/Sub Lite docs for more details on how to activate Pub/Sub Lite for your project, as well as guidance on how to choose between Cloud Pub/Sub and Pub/Sub Lite.
