Module partition_metadata 

Reads and parses partition Parquet footers directly from object storage

Functions

load_partition_metadata

Read and parse a partition’s parquet footer directly from object_store — the sole partition-metadata read path. Checks and backfills the shared MetadataCache parsed-lookaside: on a cache hit this returns immediately, on a miss it reads the footer from object_store (which may itself be L1-cache-backed) and stores the parsed result before returning it.
