easy📝 Conceptual Q1 of 15
Node.js - Worker Threads
Which advantage does the worker pool pattern provide when handling multiple CPU-bound tasks in Node.js?
AIt allows reusing a fixed number of workers to process tasks concurrently, reducing overhead.
BIt automatically scales the number of workers based on network latency.
CIt eliminates the need for asynchronous programming in Node.js.
DIt ensures tasks are executed sequentially to avoid race conditions.
Step-by-Step Solution
Solution:

  1. Step 1: Understand worker pool pattern

    The pattern involves creating a fixed number of worker threads to handle multiple tasks.

  2. Step 2: Identify benefits

    Reusing workers avoids the overhead of creating and destroying threads repeatedly.

  3. Final Answer:

    It allows reusing a fixed number of workers to process tasks concurrently, reducing overhead. -> Option A

  4. Quick Check:

    Worker pools optimize resource usage by reusing threads [OK]
Quick Trick: Worker pools reuse threads to handle tasks efficiently [OK]
Common Mistakes:
  • Thinking worker pools automatically scale based on network conditions
  • Assuming worker pools remove the need for async code
  • Believing worker pools force sequential task execution
