RelationMetadataProvider

trait RelationMetadataProvider extends LookupCatalog

RelationMetadataProvider provides relations with resolved metadata based on the corresponding UnresolvedRelations. It is used by Resolver to replace UnresolvedRelation with a specific LogicalPlan with resolved metadata, e.g. with UnresolvedCatalogRelation or View.

  3. abstract val relationsWithResolvedMetadata: RelationsWithResolvedMetadata

    relationsWithResolvedMetadata is a map from relation ID to the specific LogicalPlan with resolved metadata, like UnresolvedCatalogRelation or View.

    relationsWithResolvedMetadata is a map from relation ID to the specific LogicalPlan with resolved metadata, like UnresolvedCatalogRelation or View. It's filled by the specific RelationMetadataProvider implementation and is queried in getRelationWithResolvedMetadata.

  4. abstract def resolve(unresolvedPlan: LogicalPlan): Unit

    Resolve metadata for the given unresolvedPlan.

    Resolve metadata for the given unresolvedPlan. This method is called once per unresolved logical plan by the Resolver (for each SQL query/ DataFrame program and for each nested View operator).

    Returns the RelationId for the given UnresolvedRelation. Here we use relationResolution to expand the UnresolvedRelation identifier fully, so that our RelationId uniquely identifies the unresolvedRelation.

    This method is public, because it's used in MetadataResolverSuite.

    Extract catalog and identifier from a multi-part name with the current catalog if needed.

    Extract catalog and identifier from a multi-part name with the current catalog if needed. Catalog name takes precedence over identifier, but for a single-part name, identifier takes precedence over catalog name.

    Note that, this pattern is used to look up permanent catalog objects like table, view, function, etc. If you need to look up temp objects like temp view, please do it separately before calling this pattern, as temp objects don't belong to any catalog.
