Avoid Whitelist + Observed Values dimensions

Data growth issues are most prevalent in dimensions that are configured to record Whitelist + Observed Values. Since the observed values are renewed each hour on each Canister, the data volume can grow large.

Note: Define dimensions that record Whitelist + Observed Values only where necessary. Data for these dimensions can grow without bound.

If you are able to define a whitelist that captures all interesting dimension values for you, you should switch the dimension to record only from the whitelist that you defined.

Note: Discover recommends building your dimension value that is set by recording values to Whitelist Only and enabling logging of observed values. These logged values can be used to populate the whitelist and are automatically purged later. See Recommended workflow.

See Manage Events - Dimensions Tab.

A Whitelist + Observed Values configuration may be used when populating a dimension that is not dynamic or is populated by a limited set of dynamic data. For example, you might use observed values to capture a limited set of query strings associated with a small subset of hit or event occurrences.
