Streamlining Data Access for with
summary
Alluxio integrates with Ray as a distributed caching layer sitting between GPUs and object stores (S3/GCS/Azure), claiming petabyte scale and billions of files while serving tens of GB/s per worker and sub‑ms to single‑digit ms latency versus ~100 ms from S3. Benchmarks show 3.5x CV throughput, training wall time improvements like 4 hours → 1 hour or 4 weeks → 1 week, GPU utilization rising from 50% to 93%, model distribution cut from 20 to 5 minutes, and a preload command with megabyte‑level cache granularity.
