CollectionAvailability

One collection ID aggregated across all catalogs that serve it.

Functions

aggregate_collections

Aggregate the introspected supported_collections across all catalogs into a flat list of “collection -> serving catalogs.” Catalogs whose supported_collections is None (not yet introspected) contribute nothing.

catalogs_supporting

Return the IDs of every catalog whose introspected set contains collection_id. Catalogs with None (uninitialized) are excluded — we only report definite matches.

collections_by_catalog

Per-catalog view: catalog ID -> sorted list of canonical collection IDs. Catalogs with no introspection data are omitted.

unsupported_collections

Return the requested collections that no known-introspected catalog can serve. Conservative: if any catalog has unknown (None) capabilities, we don’t flag the collection (it might be served).
