BigMemory for Caching, Connections and MashZone NextGen Analytics
By default Business Analytics uses local memory for caching and the MashZone NextGen Analytics In-Memory Stores that MashZone NextGen Analytics creates. This uses BigMemory as a local client that is installed with Business Analytics and requires only your Business Analytics license. In specific cases, you must also install BigMemory Servers on one or more additional hosts and configure Business Analytics and the Integrated MashZone Server to work with them. Business Analytics requires BigMemory Servers with a BigMemory license to support:
Significant, extensible amounts of memory, most commonly for very large datasets used with
MashZone NextGen Analytics.
BigMemory Servers can be deployed in clusters, also known as Terracotta Server Arrays, that can easily be extended for scalable memory requirements.
Access to
off-heap memory.
BigMemory Servers also can manage memory outside of heap both for better scalability and performance improvements.
Access to
In-Memory Stores created and populated dynamically by external systems.
BigMemory manages the In-Memory Stores created dynamically by other systems and makes connection information available to Business Analytics through the Terracotta Management Console (TMC) to allow Business Analytics to work with this data. Apama, for example, dynamically creates distributed stores for the Apama MemoryStore which Business Analytics can connect to and query.
Distributed caching when
Business Analytics is deployed in clusters.
With clusters, some of the interal Business Analytics caches must be distributed and managed by BigMemory Servers.
MashZone feeds that use
BigMemory connections as a data source.

Analytics In-Memory Stores for an overview and links to additional information on
MashZone NextGen Analytics In-Memory Stores.
You also need to provide configuration and connection information for In-Memory Stores that are created by other systems or stores created by MashZone NextGen Analytics that need different settings than the defaults. For more information on these tasks, see:
