Description: Transaction recovery refers to the process of restoring a system to a consistent state after a failure. This concept is fundamental in distributed systems, where multiple nodes work together to perform operations. Transaction recovery ensures that in the event of an error, such as a system crash or network interruption, data is not lost and system integrity is maintained. To achieve this, techniques such as transaction logging are used, which allow tracking all operations performed, and consensus algorithms, which ensure that all nodes in the system agree on the state of transactions. Transaction recovery focuses not only on data restoration but also on the ability of systems to continue operating efficiently and reliably, minimizing downtime and ensuring that operations are completed correctly. This process is essential in critical applications, such as financial and e-commerce systems, where data loss or inconsistency can have severe consequences. In summary, transaction recovery is a key component in the architecture of distributed systems, ensuring data reliability and consistency in complex and dynamic environments.
