Distributed Databases Questions
Data recovery in a distributed database refers to the process of restoring the database to a consistent and usable state after a failure or error occurs. This involves recovering lost or corrupted data, ensuring data integrity, and bringing the database back online.
Concurrency in a distributed database refers to the ability of multiple users or processes to access and manipulate the database simultaneously without interfering with each other. It involves managing concurrent transactions and ensuring that they do not result in data inconsistencies or conflicts. Techniques such as locking, timestamping, and conflict resolution mechanisms are used to achieve concurrency control in distributed databases.
