Commit Protocols

Commit protocols are methods used in distributed systems to ensure all participating computers agree on a transaction's outcome—either all commit (approve) or all abort (cancel). They coordinate decisions so that even if some systems fail or messages are delayed, the data remains consistent and reliable. Think of it like a group decision: everyone must agree before finalizing an action, preventing conflicting updates. This process safeguards data integrity across multiple locations, ensuring that either all parts of the system reflect the change or none do, maintaining consistency despite failures or errors.
