Two-Phase Commitment
Two-Phase Commit is a process used in computer systems to ensure all parties involved in a transaction agree and work together reliably. It happens in two steps: first, the coordinator asks all participants if they are ready to proceed (vote). If everyone agrees, the coordinator then confirms everyone should complete the transaction. If any participant says no, the transaction is canceled. This method ensures data consistency across systems, preventing partial updates that could cause errors or conflicts. It’s like a group decision-making process that guarantees all members agree before action is taken.
