Class GlobalRowStoreSchema

java.lang.Object

com.bigdata.sparse.Schema

com.bigdata.sparse.GlobalRowStoreSchema

All Implemented Interfaces:

Externalizable, Serializable

public class GlobalRowStoreSchema
extends Schema

Schema for the SparseRowStore used as a global row store for named property sets within the federation. This schema only declares the primaryKey, NAME, and a single property value, VALUE.

Applications may simply declare their own property names or they may declare their own Schema. Applications are responsible for ensuring that the primaryKey values are globally distinct, e.g., by use of a namespace convention.
