This topic presents basic examples to help you get comfortable with the features of MashZone NextGen Analytics and the Real-Time Analytics Query Language (RAQL).
Additional query techniques for RAQL are discussed in RAQL Queries and Working with MashZone NextGen Analytics In-Memory Stores.
For some simple examples of mashups and information on the Mashup Samples project, see RAQL Samples.
About the Real-Time Analytics Query Language Examples
Many of the example datasets used in this topic or other topics illustrating RAQL are available as both:
*Files in the web-apps-home/mashzone/WEB-INF/classes folder in the MashZone NextGen Server.
*Hosted resources at http://mdc.jackbe.com/prestodocs/data/file-name.
In a few cases, such as examples for snapshots, you must provide some initial configuration or perform some steps in MashZone NextGen Hub to make the datasets used in the example available.
Note: The example datasets used in this topic do not necessarily represent actual load or throughput requirements. Base memory settings for MashZone NextGen may require tuning to provide adequate performance for actual loads. For more information, see About BigMemory and the MashZone NextGen Analytics In-Memory Stores.
First let’s take a look at a simple RAQL query.
