Threads And Concurrency Questions
The Java StampedLock class is used for providing an advanced locking mechanism that supports both exclusive and optimistic read locks. It allows multiple threads to read data concurrently while ensuring exclusive access for write operations. StampedLock also provides a mechanism called optimistic locking, where a thread can perform a read operation without acquiring a lock, and then validate if the data has been modified by another thread before proceeding. This class is useful in scenarios where there are more read operations than write operations, as it offers better performance compared to traditional locks like ReentrantReadWriteLock.
