For dynamic dimensions

For dimensions whose values are constantly changing, you may need a different approach, in which you are capturing whitelist + observed values and trimming your whitelist regularly.

This approach requires more regular management of the population of your whitelist. The remainder of the section provides an overview of the approach.

Note: Keep in mind that when observed values are enabled for capture, growth of the table containing the dimension values is not checked. Purging may be required from time to time. See Purging dimension data.
