Requires Python: >=3.8

Python Client for Pub/Sub Lite API
==================================

|stable| |pypi| |versions|

`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](https://cloud.google.com/pubsub/quickstart-console#before-you-begin) 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.

Quick Start
-----------

In order to use this library, you first need to go through the following steps:

1. `Select or create a Cloud Platform project.`_
2. `Enable billing for your project.`_
3. `Enable the Pub/Sub Lite API.`_
4. `Setup Authentication.`_

.. _Select or create a Cloud Platform project.: https://console.cloud.google.com/project
.. _Enable billing for your project.: https://cloud.google.com/billing/docs/how-to/modify-project#enable_billing_for_a_project
.. _Enable the Pub/Sub Lite API.:  https://cloud.google.com/pubsub/lite
.. _Setup Authentication.: https://googleapis.dev/python/google-api-core/latest/auth.html

Installation
~~~~~~~~~~~~

Install this library in a `virtualenv`_ using pip. `virtualenv`_ is a tool to
create isolated Python environments. The basic problem it addresses is one of
dependencies and versions, and indirectly permissions.

With `virtualenv`_, it's possible to install this library without needing system
install permissions, and without clashing with the installed system
dependencies.
