What are the drawbacks of lock-free techniques?

Lock-free techniques can lead to complexity in implementation, increased overhead, and potential for subtle bugs.

Can you explain why complexity is a drawback?

Sure! The complexity arises from the need to manage concurrent access without locks, which can make the code harder to understand and maintain.

What about performance issues? Are they common?

Yes, performance issues can occur, especially under high contention, where the overhead of managing lock-free structures can negate their benefits.

Are there specific scenarios where lock-free techniques are not recommended?

Absolutely! They are often not recommended in scenarios with low contention or when the overhead outweighs the benefits of concurrency.

What alternatives exist to lock-free techniques?

Alternatives include traditional locking mechanisms, optimistic concurrency control, and other synchronization techniques.
