What are some common challenges in implementing distributed concurrency control mechanisms, and how can they be addressed?

When it comes to the administration of multiprogramming, multiprocessing, and distributed computing computer settings, consistency is an essential component in the design of operating systems. Analyze the idea of concurrency, as well as the four design and management problems that arise when there are several users accessing the same data at the same time.

What techniques can be employed to mitigate the overhead of thread creation and destruction in a dynamically multithreaded system?

What does concurrency control imply? What role does it play in distributed systems? OR How can distributed transactions be controlled for concurrency? Explain.
