Method Details

getOrigin

T getOrigin()

Returns the original, unresolved metadata object from the Catalog.

This method might be useful if catalog-specific object instances should be directly forwarded from the catalog to a factory.

getResolvedSchema

ResolvedSchema getResolvedSchema()

Returns a fully resolved and validated ResolvedSchema.

Connectors can configure themselves by accessing ResolvedSchema.getPrimaryKey() and ResolvedSchema.toPhysicalRowDataType().

getSchema

@Deprecated
default TableSchema getSchema()

Deprecated.

This method returns the deprecated TableSchema class. The old class was a hybrid of resolved and unresolved schema information. It has been replaced by the new ResolvedSchema which is resolved by the framework and accessible via getResolvedSchema().
