All Implemented Interfaces:

java.io.Serializable
```
public class CoGbkResultSchema
extends java.lang.Object
implements java.io.Serializable
```
A schema for the results of a CoGroupByKey. This maintains the full set of TupleTags for the results of a CoGroupByKey and facilitates mapping between TupleTags and RawUnionValue tags (which are used as secondary keys in the CoGroupByKey).
