The MashZone NextGen Analytics In-Memory Stores is an in-memory store to support easy, quick access to large datasets for analysis using RAQL. This in-memory store in managed by the BigMemory Add-On. Datasets or query results are stored and retrieved using EMML extension statements in mashups.

Storing datasets or query results provides better performance, in many cases, when the dataset is used in several mashups. It is also useful for datasets with frequent or continuous updates where appending updates is appropriate.
