Achieving atomic operations: By utilizing the “getset” command, atomic operations can be achieved, allowing the simultaneous retrieval of the original value while setting a new value to avoid data inconsistency issues in a multi-threaded environment.
Counter implementation: The functionality of a counter can be achieved using the getset command, such as implementing increment and decrement operations on a specific value.
Cache Updating: You can use the getset command to ensure data consistency when updating the cache, by first getting the original value, then updating the cache, thus avoiding data corruption caused by concurrent updates.
Implementing a distributed lock: Using the getset command can achieve a distributed lock, ensuring that only one client can acquire the lock at a time through atomic operations.
Implementing simple optimistic locking:
Using the getset command can implement simple optimistic locking by comparing the old value obtained with the expected value to determine if it has been modified by another client.
