Impacts of capturing observed values

To begin populating a newly created dimension, use of whitelists only is recommended because the data volume for capturing observed values can become problematic.

Note: Even if you created a whitelist to normalize observed values, the entire set of observed values is still captured to the database. In Whitelist + Observed Values, the whitelist functions only to normalize values. It does not filter the data set that is written to the database. Enabling the capture of observed values allows these values to be recorded into the database without limit.

Unbounded dimensions can affect the Discover solution in the following ways:

  • Cleared growth of the REPORTS database
  • Bottlenecks in the Data Service and Portal
  • Performance in the Event Manager, as well as the Portal and user client UI
