Depending on the type of indexes you want to build, WebSphere® eXtreme Scale Client provides built-in plug-ins that you can add to the BackingMap
to build an index.
HashIndex
The built-in HashIndex, the com.ibm.websphere.objectgrid.plugins.index.HashIndex class,
is a MapIndexPlugin plug-in that you can add into
BackingMap to build dynamic indexes.
This class supports both the MapIndex and MapRangeIndex interfaces. Defining and implementing indexes
can significantly improve query performance.
