Netflix halves Cassandra read latency to ms with dynamic partition splitting
Netflix’s TimeSeries platform now detects Cassandra partitions that exceed a byte‑threshold and automatically splits them, routing reads to the new child partitions. The metadata‑driven approach collapses read latency from seconds to single‑digit milliseconds on petabyte‑scale workloads, improving user‑facing latency and protecting clusters from GC spikes.
