Method Detail

builder

public static SparkProcedures.ProcedureBuilder builder()

parameters

public ProcedureParameter[] parameters()

Description copied from interface: Procedure

Returns the input parameters of this procedure.

outputType

public org.apache.spark.sql.types.StructType outputType()

Description copied from interface: Procedure

Returns the type of rows produced by this procedure.

call

public org.apache.spark.sql.catalyst.InternalRow[] call(org.apache.spark.sql.catalyst.InternalRow args)

Description copied from interface: Procedure

Executes this procedure.

Spark will align the provided arguments according to the input parameters defined in Procedure.parameters() either by position or by name before execution.

Implementations may provide a summary of execution by returning one or many rows as a result. The schema of output rows must match the defined output type in Procedure.outputType().

Parameters:

args - input arguments

Returns:

the result of executing this procedure with the given arguments

description

public java.lang.String description()

Description copied from interface: Procedure

Returns the description of this procedure.
