Summary

Redpanda's introduction of tiered storage aims to efficiently unify historical and real-time data while reducing costs and improving reliability. By leveraging cloud object stores like Amazon S3 and Google Cloud Storage, Redpanda addresses data center reliability issues, enabling infinite data retention and decoupling storage capacity from the cluster's load capacity. This allows for more scalable and cost-effective infrastructure, as well as enhanced disaster recovery capabilities. The tiered storage architecture consists of components for both writing and reading data, such as the scheduler_service and remote_partition, which manage data uploads and retrievals from the cloud. The system uses metadata to ensure consistency and enables smart data retention by tracking uploaded segments. Future enhancements include full cluster recovery, faster data balancing, and the development of analytical clusters with read-only access to archived data, promoting elasticity and workload isolation. Overall, tiered storage offers developers and operators greater flexibility and efficiency in handling large volumes of data.
