Overview ¶
Package query groups the storage library's read seam and its language adapters.
Sub-packages:
- fetch: the dual-shape Request/Fetcher/Iterator contract — the language-agnostic seam every embedder query engine drives and every backend implements. This is the library's query surface (exposed via Storage.Fetcher); the storage library does not implement query languages.
- promql: an OPTIONAL adapter bridging the fetch contract to the Prometheus storage.Queryable, for embedders that drive the Prometheus PromQL engine. It is the only package importing github.com/prometheus/prometheus.
See ARCHITECTURE.md for the query layer's current state.
