How do read-write locks work in multi-threaded applications?

Can you explain how read-write locks function in multi-threaded applications?

Sure! Read-write locks allow multiple threads to read data simultaneously while ensuring exclusive access for writing.

What are the advantages of using read-write locks over regular locks?

The main advantage is improved performance. Read-write locks allow concurrent reads, which can significantly speed up operations when reads are more frequent than writes.

Are there any downsides to using read-write locks?

Yes, they can introduce complexity and potential for deadlocks if not managed properly. They also may have overhead compared to simple locks.

In what scenarios would you recommend using read-write locks?

They are ideal in scenarios with high read-to-write ratios, such as databases or caching systems, where reads are much more common.
