Using Distributed Locking To Solve Race Conditions (and why a simple solution works better)

Milan discusses ensuring uniqueness in concurrent environments by tackling race conditions with distributed locking. He illustrates the problem using a user registration example and then explores various solutions, including in-memory locks, semaphores, and database advisory locks. The most effective and straightforward solution presented is using a unique constraint or index in the relational database, which ensures uniqueness without significantly reducing concurrency.
