ScyllaDB Open Source 5.2: With Raft-Based Schema Management

ScyllaDB Open Source 5.2, building on the 2022 major release, introduces significant updates including Raft-based strongly consistent schema management, which enhances performance, stability, and ease of use by serializing schema management operations via the Raft consensus algorithm. This release addresses over 100 issues and empowers users to perform concurrent schema changes safely, with schema propagation occurring more swiftly. The update also sees the promotion of Time To Live (TTL) for the ScyllaDB's DynamoDB API (Alternator) to production readiness, allowing configurable expiration delays. Enhancements include the detection of large collections to avoid performance degradation, automated management of tombstone garbage collection, and improvements to prevent timeouts when processing extensive tombstone sequences. Additionally, secondary indexes can now be applied to collection columns, enhancing data retrieval capabilities. These updates, alongside various other improvements in performance, stability, and operational efficiency, make ScyllaDB 5.2 a robust choice for NoSQL database solutions.
