Delta Encoding
Delta encoding is a data compression technique that stores or transmits only the differences (deltas) between sequential data versions, rather than the full data each time. It is widely used in version control systems, database replication, and network protocols to reduce storage and bandwidth requirements. By encoding changes incrementally, it enables efficient updates and synchronization of data across systems.
Developers should learn delta encoding when building systems that require efficient data synchronization, such as version control (e.g., Git), database replication, or file backup solutions. It is particularly useful in scenarios with frequent small updates to large datasets, as it minimizes resource usage and speeds up data transfer. For example, in collaborative editing tools or IoT device updates, delta encoding reduces latency and costs by transmitting only changed portions.
