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 theGoogle Pub/Sub Lite docsfor 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.
Install this library in avirtualenvusing pip.virtualenvis a tool to
create isolated Python environments. The basic problem it addresses is one of
dependencies and versions, and indirectly permissions.
Withvirtualenv, it’s possible to install this library without needing system
install permissions, and without clashing with the installed system
dependencies.
