In the 80s, data was written to local disks, then moved to the cloud, causing new issues. The local-first movement aims to bring data back to users while leveraging the internet. A proposed data exchange format involves changes indexed by clients, separate files for large data, and unique URLs. Benefits include easy replication and detailed documentation. Implementation involves database tables or directories in file systems. Online services can use a mix of approaches, with potential for improvement in data size control, compression, and other areas. The local-first method offers simplicity, flexibility, and adaptability for future technologies. Watch Martin Kleppmann’s talk for more insights.
