mParticle collects data from all your platforms and data connections and connects it to all of your team’s tools and systems. All collected data is stored in mParticle, in case you need to run data replays (re-ingesting data with help from mParticle Support). Additionally, mParticle makes all data available for evaluation in Audiences and Calculated Attributes. However, many events and the data related to them may not be needed for these evaluations depending on how you use Audiences or Calculated Attributes. With Tiered Events, you can choose to store data but not evaluate it, which may improve performance.

You can use this number to, for example, identify events that you may want to mark as Store Only and which will be easy to remove from the calculated attribute or audience definition so that you can change to Store Only.
After you check all the issues in the following section, use Set Event to Store Only to change event tiers.

You must have the Admin and Compliance role to change event tiers.
