Class BinSedesTuple

java.lang.Object

org.apache.pig.data.AbstractTuple

org.apache.pig.data.DefaultTuple

org.apache.pig.data.BinSedesTuple

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable, java.lang.Iterable<java.lang.Object>, org.apache.hadoop.io.Writable, org.apache.hadoop.io.WritableComparable, Tuple

@InterfaceAudience.Private
public class BinSedesTuple
extends DefaultTuple

This tuple has a faster (de)serialization mechanism. It to be used for storing intermediate data between Map and Reduce and between MR jobs. This is for internal pig use only. The serialization format can change, so do not use it for storing any persistant data (ie in load/store functions).
