Global controls for managing dimension data
To prevent unbounded growth of the database tables that are used to store dimension values, Discover enforces the automated trimming of dimension values.
When a dimension is configured to capture and store observed values, each instance of a detected value is stored in the database, which means that the database can grow without limit. The automation of dimension value trimming is intended to place an upper limit on the volume of data stored in your system for each dimension and to prevent total consumption of available disk space.
