Description: Node repair is the process of correcting inconsistencies in data between replicas in a distributed database cluster. This process is essential for maintaining data integrity and availability in distributed systems, where multiple nodes may store copies of the same information. In such systems, data is distributed across nodes using a replication approach, meaning each piece of data can be present on several nodes. However, due to network failures, node outages, or write issues, discrepancies may arise between replicas. Node repair is carried out by comparing the data stored on different nodes and synchronizing any inconsistencies detected. This process not only helps ensure that all nodes have the same information but also optimizes system performance by removing obsolete or corrupt data. Repair can be scheduled to run automatically or initiated manually, and it is a crucial part of regular maintenance for distributed database clusters to ensure their efficient and reliable operation.
