datasynchronization
Datasynchronization, also known as data synchronization, is the process of ensuring that two or more data sources reflect the same information over time. It involves detecting changes, propagating updates, and reconciling divergent copies. Synchronization can be one-way, where a primary source pushes changes to replicas, or two-way, where updates may occur at multiple locations and must be reconciled to maintain consistency. It is used across databases, file systems, cloud services, and mobile or edge devices.
Techniques include log-based replication and change data capture (CDC), which record updates as events; streaming replication
Key considerations are data identity and versioning, idempotent operations, ordering guarantees, and schema evolution. Data protection
Applications include database replication, online file synchronization services, mobile offline editing, IoT data collection, and collaborative
