Improved Performance in ScyllaDB Open Source 3.0: Streaming and Hinted Handoffs

ScyllaDB Open Source 3.0 introduces significant enhancements in performance and functionality for the NoSQL database, with key improvements in streaming and hinted handoff processes. The new release optimizes the data streaming process between nodes by replacing the previous RPC-based method with a specialized interface that reduces overhead, resulting in faster operations such as node additions and decommissioning. These changes are demonstrated to improve streaming performance by up to 22% over the previous version, ScyllaDB 2.3. Additionally, the introduction of the Hinted Handoff feature reduces data discrepancies during node outages, decreasing the need for on-the-spot data reconciliation during QUORUM consistency reads and improving tail latencies by up to 62%. These advancements, alongside the transition of features like Materialized Views and Secondary Indexes to production-ready status, collectively enhance the capabilities and efficiency of ScyllaDB, offering users improved data modeling and workload handling.
