multistore-path-mapping

Hierarchical path mapping for the multistore S3 proxy gateway.

Overview

Translates hierarchical URL paths into flat internal bucket names while configuring list rewrite rules so S3 XML responses display the expected key structure.

For example, with bucket_segments: 2 and separator: "--":

• Request to /acme/data/file.parquet resolves to internal bucket acme--data with key file.parquet
• LIST responses rewrite keys to show the hierarchical structure

Usage

use multistore_path_mapping::{PathMapping, MappedRegistry};

let mapping = PathMapping {
    bucket_segments: 2,
    bucket_separator: "--".into(),
    display_bucket_segments: 1,
};

// Wrap any BucketRegistry to add path-based routing:
let registry = MappedRegistry::new(inner_registry, mapping);
