In the video, I explained how the standard count plus plus operation is not Atomic and demonstrated it using Go code with a global variable. I then implemented pessimistic locking using a mutex to ensure that count plus plus is executed by only one thread at a time, making the final value consistently 1 million. I highlighted the trade-off between correctness and performance in multi-threaded programming, emphasizing the importance of keeping critical sections minimal for optimal parallelism. Pessimistic locking is crucial for correct multi-threaded programs, even though it can impact performance.
