This is a Python 3 library for managing a task queue over Google Cloud Pub/Sub. Tasks are defined in Protocol Buffer messages, so the requestor and worker code versions do not need to be kept perfectly in sync. This is not an officially supported Google product.
In addition to the dependencies listed in setup.py, the
protobuf compiler and well-known types
(Debian: sudo apt install protobuf-compiler libprotobuf-dev) are required.
While this library can be used with the default configuration for topics and subscriptions, we recommend setting a retry policy on the Pub/Sub subscription that Proto Task Queue is reading messages from. Specifically, we recommend setting the minimum retry delay to a value greater than 0 so messages aren't immediately retried after failing for any reason. You may need to customize your retry delay based on your application's particular messages and latency requirements. If you're looking for a suggestion, we recommend starting with 60 seconds.
