Asynchronous Control Flow Patterns: Ordered Parallel Execution
Explore how to implement ordered parallel execution in Node.js streams to keep data output in the original input order while processing tasks concurrently. Understand the use of buffers to reorder chunks and the benefits of using the parallel-transform package for predictable memory usage and efficient asynchronous stream handling.

The parallel streams that we created previously may shuffle the order of the emitted data, but there are situations where this is not acceptable. Sometimes, in fact, it’s necessary to have each chunk emitted in the same order in which it was received. However, we can still run the transform function in parallel; all we have to do is sort the data emitted ...
