Design for Unreliable Connections
Explore how to design Phoenix Channels that handle unreliable internet connections and server restarts. Understand strategies for managing channel subscriptions, preserving critical data in persistent storage, and the message delivery guarantees provided by Phoenix Channels. This lesson helps you build more robust real-time applications that recover from disconnections and unpredictable network issues.
We'll cover the following...
In the previous section, we learned how to restrict access to a Channel-based application using authentication. We covered enough to build basic Channel applications, but there’s still more we need to know to build full-featured Channel applications. This section will look at concepts such as Channels in a cluster of servers, how to customize Channel behavior, and how to write tests for Channels.
First, we’ll cover the unreliable nature of internet connections and consider how we can build applications that survive the strange things that can happen with real users. Flaky internet connections, bugs in an ...
