MVCC in Distributed Systems

Multi-Version Concurrency Control (MVCC) is a method used in distributed systems to manage simultaneous data access. It creates multiple versions of data items, allowing multiple users to read and write without conflicts. When a user reads data, they see a consistent snapshot of the information at a specific moment, while others can still update the data independently. This approach ensures high concurrency and data accuracy, reducing delays or locks, making the system efficient and reliable even with many users accessing data simultaneously.
