Improve Performance with Streams
Explore how to improve Elixir application performance by using Streams for lazy evaluation and efficient data processing of large files. Learn to replace eager computations with Stream and File.stream! to process CSV files faster and understand how concurrent processing with Flow can further optimize your code.

Streams
We know that the Stream data structure is lazily evaluated and allows us to process data only when needed. The Stream module has lazy implementations of map/2, filter/2, and other functions. We can use Stream.map/2 and Stream.filter/2 to replace their Enum counterparts, but what about reading and parsing the file?
Use File.stream!
Don’t worry, Elixir has us covered. The File module ...
