In the current global enterprise business environment, with the millions
of applications running across mobile phones and tablets, mobile brings more business opportunities for
value added services but also brings more challenges to existing
systems. Data is being accessed at a rapidly increasing rate to service
mobile applications and the workload is becoming a burden to back-end
servers. The solution to this problem is caching, and IBM ® WebSphere ® eXtreme Scale or the WebSphere DataPower ® XC10 Appliance can cache frequently used... [More]
The InverseRangeIndex sample is provided for a quick introduction to the Inverse Range Index feature. It consists of shell and batch scripts designed to start a simple grid with very little customization needed. The sample shows how to use WebSphere eXtreme Scale for indexing Range style data that can be looked up efficiently. This sample can be run with WebSphere eXtreme Scale or IBM DataPower XC10 Appliance. If you have data contains range attributes, you can use Inverse Range index to index over range attributes and use index to search... [More]
