Add support for persisting OTel resource/scope attributes alongside time series data in TSDB, enabling the info() PromQL function to enrich metrics with resource context without relying on target_info metric scraping. Storage layer: - Add ResourceUpdater interface with UpdateResource() to storage.Appender - Add ResourceContext to AppendV2Options for passing resource attributes - Add ResourceQuerier interface for querying stored resource attributes - Add EntityData type for passing OTel entity information through storage TSDB seriesmetadata subsystem: - Add Entity type with OTel entity data model (type, ID, description) - Add ResourceVersion with versioned identifying/descriptive attributes - Add VersionedResource for tracking attribute changes over time - Add MemResourceStore for in-memory resource storage with versioning - Extend Parquet schema with resource namespace, nested attribute lists, and entity rows - Add zstd compression, row sorting, and footer metadata to Parquet writer OTLP integration: - Extend CombinedAppender to extract and persist resource attributes from OTLP ResourceMetrics during ingestion PromQL info() function: - Rewrite to use stored resource attributes instead of fetching target_info series, with attribute name translation via LabelNamer mappings Web API: - Add /api/v1/resources endpoint for querying stored resource attributes - Support format=attributes for autocomplete use cases - Add OpenAPI documentation for the new endpoint Signed-off-by: Arve Knudsen <arve.knudsen@gmail.com> |
