Node.js Cluster Module vs Worker Threads

What are the main differences between Node.js Cluster Module and Worker Threads?

The Node.js Cluster Module allows you to create multiple child processes that share the same server port, while Worker Threads provide a way to run JavaScript operations in parallel threads, allowing for better performance in CPU-intensive tasks.

When should I use the Cluster Module instead of Worker Threads?

Use the Cluster Module when you need to handle multiple connections efficiently, like in a web server. Worker Threads are better for CPU-bound tasks that require parallel processing.

Can you give an example of when to use Worker Threads?

Sure! If you have a task that involves heavy computations, like image processing or data analysis, using Worker Threads can help keep your main thread responsive.

Are there any limitations to using Worker Threads?

Yes, Worker Threads have some limitations, such as the need for serialization of data when passing messages between threads, and they may not be suitable for all types of applications.
