Python, in all of its greatness, is often dismissed when needing to write performant and distributed applications. It’s considered to be slow and not suited for the task. In this course, you will find that with the right implementation of Python, you can write applications that scale horizontally, perform well, and are distributed. 

To kick things off, you’ll learn about CPU scaling, concurrency, and event loops, all of which are crucial for implementing a distributed system. After that, you’ll move on to queue-based distribution, lock management, and group memberships, which are fundamental concepts for maintaining availability and consistency in distributed applications.

In the last half, you’ll learn how to build a REST API, how to deploy your app to a PaaS, and how to optimize your application's performance.

By the end of this course, you’ll be more productive with Python, you’ll be able to write faster applications that are distributed, and you’ll have a great new skill that is highly coveted.

The Hacker's Guide to Scaling Python

_Tooz_ provides a capability mechanism on top of the group feature. When joining a
group, a member can specify what its capabilities are. It can also update them later as needed.

Capabilities are any simple data structure that your program needs to share. It can be as simple as a string and as complicated as a nested dictionary. The typical usage of this data structure is to pass information about the member, such as its processing power or its feature set. It allows filtering members based on their functionality or weighing them differently based on their computing power.

# Joining a group with a capability set
The example below shows a complete example of joining a group with a capability set. In this example, each client can provide a mood when joining a group. All members can then get member capabilities and retrieve their moods.
