KurrentDB v25.0 introduces the Archiving feature, allowing users to move older data to external storage like S3. This practice reduces primary disk space usage and optimizes cost by keeping frequently accessed data (hot) on local disks while storing less accessed data (cold) on cheaper, slower storage. The Archiving feature improves scalability by eliminating volume size limits and simplifies configuration with user-defined retention policies. The implementation involves an Archiver node to manage data uploads to the archive. Detailed configurations and S3 authentication methods are covered.
