- abstract def bind(inputType: StructType): BoundProcedure
Binds this procedure to input types.
Binds this procedure to input types.
If the catalog supports procedure overloading, the implementation is expected to pick the best matching version of the procedure. If overloading is not supported, the implementation can validate if the input types are compatible while binding or delegate that to Spark. Regardless, Spark will always perform the final validation of the arguments and rearrange them as needed based on
reported parameters.The provided
inputTypeis based on the procedure arguments. If an argument is passed by name, its metadata will indicate this withProcedureParameter#BY_NAME_METADATA_KEYset totrue. In such cases, the field name will match the name of the target procedure parameter. If the argument is not named,ProcedureParameter#BY_NAME_METADATA_KEYwill not be set and the name will be assigned randomly.- inputType
the input types to bind to
- returns
the bound procedure that is most suitable for the given input types
- abstract def name(): String
Returns the name of this procedure.
Returns the name of this procedure.
