Enum Class MLContext.ExecutionType

java.lang.Object

java.lang.Enum<MLContext.ExecutionType>

org.apache.sysds.api.mlcontext.MLContext.ExecutionType

All Implemented Interfaces:

Serializable, Comparable<MLContext.ExecutionType>, Constable

Enclosing class:

MLContext

public static enum MLContext.ExecutionType
extends Enum<MLContext.ExecutionType>

The different types of execution environments supported by SystemDS. The default execution type is DRIVER_AND_SPARK. DRIVER refers to all operations occurring in the local driver JVM. SPARK refers to all operations occurring on Spark. HADOOP refers to all operations occurring on Hadoop. DRIVER_AND_SPARK refers to operations occurring in the local driver JVM and on Spark when appropriate. DRIVER_AND_HADOOP refers to operations occurring in the local driver JVM and on Hadoop when appropriate.
