Plug-ins for indexing data

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.
