Netflix cuts Tiered TimeSeries costs by swapping Kafka/Flink for native Cassandra reads
Netflix’s TimeSeries abstraction now pulls older immutable slices directly from Cassandra instead of replaying them through Kafka and Flink pipelines. This native‑read path lets them off‑load petabytes of cold data to cheap S3 while keeping sub‑second query latency, reducing operational complexity and storage spend.
