IAsyncEnumerable in C# 8

Camilo Reyes shows off an interface:

The IAsyncEnumerable interface was introduced to address the limitations of the IEnumerable interface and the Task class. This way, you can stream asynchronous data and process it efficiently as soon as it becomes available.

In this take, you will learn how to work with IAsyncEnumerable to asynchronously stream a big table and extract the data in a ETL process. You will also learn the difference between IAsyncEnumerable and IEnumerable and how to use IAsyncEnumerable in your everyday work. Then, you will look at comparisons between the two different approaches and why one is better than the other in certain scenarios.

Read on for a demonstration and dive into how IAsyncEnumerable implementations compare to IEnumerable in terms of memory utilization.
