class SageMakerProtobufFileFormat extends FileFormat with DataSourceRegister

A Spark FileFormat for serializing Dataframes of labeled vectors to the Amazon Record protobuf file format encoded in RecordIO.

To write records from a DataFrame in this file format, run dataframe.save .format("sagemaker") .option("labelColumnName", "myLabelColumn") .option("featuresColumnName", "myFeaturesColumn") .save("my_output_path")
