IMetabaseCache

Description

The IMetabaseCache interface contains properties and methods that are used to work with repository cache.

Comments

Access to repository cache is returned by the IMetabase.Cache property.

When working with objects data caching is implemented in repository cache for faster access to data. When caching, temporary object copies that contain frequently used data are created on the user computer. If an object has parameters copies are created for each set of parameters with which an object is opened. Data caching is supported by tables, dictionaries, time series databases, and global variables.

Repository cache also stores references to used objects. A reference contains object address in memory but not its data or metadata. References are used to provide interaction between objects in platform kernel and when working with objects in application code.

Repository cache is stored and used within the same repository connection.
