Comments

Mutex is an object that implements mechanism of synchronization that provides access to data only from one stream at a time. In the current implementation mutex is supported by matrix and matrix iterator, which are obtained on the basis of cached cube data (cube is calculated in the CubeInstanceDestinationExecutorOptions.Cached mode).

The use of mutex is required if the developed code supposes working with cached cube data, but code is executed via web services of BI server of platform. On working of BI server cube cache is loaded to memory once, and all objects configured to work with the cube, will use common cache. In Foresight Analytics Platform tools, lockings are controlled automatically. When working with cubes in Fore locking should be controlled on the application level.
