pip install alluxiopip install cephpip install alluxiopip install cephPython data engineers use Alluxio to accelerate PySpark pipelines that repeatedly read the same S3 or HDFS data. By mounting S3 data into Alluxio's memory cache, subsequent Spark reads hit in-memory cache instead of object storage — reducing read latency from seconds to milliseconds for iterative ML training or repeated dashboard queries.
Python data engineers in on-premise or private cloud environments use Ceph's S3-compatible RADOS Gateway as a drop-in replacement for AWS S3 — boto3 and awswrangler work unchanged by pointing them at the Ceph endpoint URL. CephFS is mounted as a shared file system that multiple Python pipeline worker nodes read from and write to simultaneously.
