How do regular queues handle concurrency?

Can you explain how regular queues handle concurrency?

Regular queues manage concurrency by ensuring that tasks are processed in a first-in, first-out (FIFO) manner, preventing conflicts.

What happens if multiple tasks try to access the queue at the same time?

When multiple tasks access the queue simultaneously, most implementations use locking mechanisms to ensure that only one task can modify the queue at a time.

Are there any performance issues with this approach?

Yes, locking can lead to bottlenecks, especially if tasks take a long time to process, which can slow down overall throughput.

How do advanced queues improve on this?

Advanced queues often use techniques like partitioning or sharding to allow multiple concurrent accesses without locking, improving performance.
