Netflix Cuts Cassandra Read Latency from Seconds to Milliseconds with Dynamic Partition Splitting

Leela Kumili — Mon, 06 Jul 2026 14:24:00 GMT

Netflix engineers introduced dynamic partition splitting for Cassandra to address wide partitions in time series workloads. The metadata-driven approach detects oversized partitions, splits them smaller units, and routes reads across child partitions. Netflix reported lower read latency from seconds to milliseconds, reduced timeouts, and improved cluster stability while maintaining transparency.

AWS Introduces Amazon S3 Annotations

Renato Losio — Sun, 05 Jul 2026 08:55:00 GMT

AWS recently announced Amazon S3 Annotations, a feature that lets teams attach rich, searchable context such as summaries, classifications, compliance data, or AI-generated insights directly to S3 objects. Annotations can be updated independently of the object and queried across datasets, reducing the need for separate metadata systems.
