Alluxio S3 API
S3-compatible REST API exposed by every Alluxio worker (HTTP port 29998, HTTPS 29996) that lets applications built for Amazon S3 read and write cached data without code changes. Path-style requests only; mount points are surfaced as S3 buckets. Endpoint is deployment-specific (runs on the customer's self-hosted Alluxio cluster), so no public production baseURL exists.
