What are the downsides of lock-free queues?

What are the downsides of lock-free queues?

Lock-free queues can lead to issues like complexity in implementation, potential for starvation, and difficulty in debugging.

Can you explain what starvation means in this context?

Starvation occurs when certain threads are perpetually denied access to the queue, often due to priority issues or contention.

Are there any performance trade-offs with lock-free queues?

Yes, while they can reduce contention, they may also incur higher overhead due to the need for atomic operations and memory management.

How do lock-free queues compare to traditional queues?

Lock-free queues can offer better performance in multi-threaded environments, but they are more complex and harder to implement correctly.

What are some alternatives to lock-free queues?

Alternatives include traditional lock-based queues, message passing systems, or using higher-level abstractions like actor models.
