Description: Node synchronization is the process of ensuring that data is consistent across all nodes in a distributed database cluster. This process is fundamental for maintaining data integrity and availability in distributed systems, where multiple nodes may store copies of the same information. In distributed databases, synchronization is achieved through a replication mechanism that allows data to be distributed and kept up-to-date across all nodes in the cluster. Whenever a write operation is performed, the data is replicated across several nodes according to the configured replication strategy. This not only enhances availability but also allows the system to continue functioning even if some nodes fail. Node synchronization also involves conflict resolution, as different nodes may receive updates simultaneously. To handle this, distributed databases often employ time-based approaches, where data versions are compared and resolved according to their timestamps. This process is crucial to ensure that all nodes have a coherent view of the data, which is essential for applications requiring high availability and performance, where data consistency is vital for transaction trust and security.
