A cache stored in external Interstage Terracotta BigMemory Max (hereafter referred to as "Terracotta") can be referenced as a named window from the complex event processing of BDCEP. As data in the window is actually external to the system, this window is also called a Virtual Data Window.
In the example below, a cache stored in Terracotta is referenced, and the referenced data is joined with input events and then passed to the output adapter.
Figure 2.5 Example of Terracotta collaboration (1)
The following example retains input events in the Terracotta cache and joins the retained cache data to other input events.

Refer to "4.4.3 Setup of Terracotta Collaboration" for information on how to set up Terracotta.
Refer to "5.4.4.3.3 Using Terracotta cache" for information on how to use a Terracotta cache from complex event processing.
Note
To use Terracotta collaboration, you must separately install Terracotta.
