mParticle collects data from all of your platforms and data connections and uses it to resolve customer identities and stitch together customer profiles. It also makes this data available to be forwarded to downstream systems, and retains it in long-term data stores that allow you to run data replays with help from mParticle Support.

\n

By default, mParticle makes all data available for evaluation. However, many events and the data related to them may not be needed for running data replays or evaluations depending on how you use Audiences or Calculated Attributes. With Tiered Events, you can choose to collect data but not store it, or to collect and store data but not evaluate it.

\n

These configurations help improve performance for all customers, and may provide cost savings for value-based pricing customers.

\n

\"List

\n

mParticle provides three event tiers. All three tiers support ingestion and forwarding of data, but provide different levels of support for storage and evaluation:

\n\n

The following table can help you decide which tier to apply to data:

If your account uses value-based pricing, you can change the default event tier for ingested events.

\n

There are two ways to modify your event tiers:

\n\n\n

\n \n \n \n \n \n \n \n Prerequisites

\n

Before you modify your event tiers using either method, ensure the following prerequisites are met:

\n\n

\n \n \n \n \n \n \n \n Modify an event tier in the UI

\n

To change the event tier using the UI:

\n
    \n
  1. Navigate to Data Platform > Data Catalog and select the event type such as Custom Events or Screen View.
    2. \n
  2. Next to the event, click the Event Tier drop-down and select a new tier.
    3. \n
  3. Click Apply.

\n\n

\n \n \n \n \n \n \n \n Modify event tiers in bulk

\n

You can make bulk modifications to your event tiers by downloading a copy of your Event Volume Report, entering your new tiers in the New Event Tier column in the downloaded file, and then re-uploading your new report to commit your changes in mParticle.

\n

To make bulk changes to your event tiers:

\n
    \n
  1. Navigate to Data Platform > Data Catalog and hover your cursor over the Event Tier tooltip.
    2. \n
  2. Click Manage Event Tiers.
    3. \n
\n

\n
    \n
  1. Select Download Event Volume Report and click Next.
    2. \n
\n

\n
    \n
  1. \n

    Under Select Event Volume Data Range, use the date picker to select one of the date range presets or enter a specific date range to include in your Event Volume Report.

    \n\n
    2. \n
\n

\n

\n
    \n
  1. After entering the date range of the event data you want included in your report, click Download Report.
    2. \n
  2. \n

    Open the Event Volume Report downloaded to your computer. Find the row for each event type you want to change the tier for, and enter the tier in the New Event Tier column. Make sure to save your changes.

    \n\n
    3. \n
\n

\n
    \n
  1. To upload your modified report, repeat steps 1-2, select Bulk Update Event Tiers, and click Next.
    2. \n
\n

\n
    \n
  1. In the Bulk Update Event Tiers modal, click Upload and select your modified Event Volume Report.
    2. \n
  2. Click Update Event Tiers to upload your modified Event Volume Report. When the upload is complete, a new Event Volume Report is automatically generated and downloaded to your computer so you can confirm that your changes were made correctly.

\n

\n \n \n \n \n \n \n \n Change the default event tier

\n

By default, mParticle assigns all event types to the Personalize tier. However, you can change the default assignment to Preserve or Connect if your account uses value-based pricing.

\n

Changing the default tier is helpful. For example, if you create a data plan with many new event types and most of them won’t be needed for real-time evaluations, you could assign them to the Preserve or Connect tier by default.

\n

To change the default event tier for a workspace:

\n
    \n
  1. In the left-hand navigation, click the Settings gear cog to open the settings menu.
    2. \n
\n

\n
    \n
  1. Click Workspaces.
    2. \n
  2. From the list of workspaces, click a workspace name to open the workspace settings dialog.\n\"UI
    3. \n
  3. Expand Defaults and use the drop-down in the Event Tiers section to choose a new default tier.
    4. \n
  4. Click Save to save your changes.
    5. \n
\n\n

After you set a default tier, all new events of all types seen in mParticle are assigned the new default tier. You can override the default tier assignment of an event type in Data Platform > Data Catalog.

\n

For example, you could change the default tier to Connect in the workspace setting and also set the tier for event type MyEvent to Personalize. Then, all new and existing events of type MyEvent are assigned the Personalize tier, while all other new events are given the new default, Connect.

\n

\n \n \n \n \n \n \n \n Event Volume Report

\n

The event volume report is a CSV file that lists all the events used in calculated attributes and audiences. It also shows data volumes for the time range you specify.

\n

The event volume report is accessible from your workspace settings:

\n
    \n
  1. Hover your cursor over the Settings gear icon in the left hand nav and click Workspaces.
    2. \n
  2. Click the Event Volume Report button in the upper right.
    3. \n
  3. Select the date range for the data you want covered in your report, then click Download Report.
    4. \n
\n

\"Sample

\n\n

The Event Volume Report displays an approximate count of each event type ingested from your inputs within a certain date range. You can use these metrics to identify event types to change to a different event tier, or event types to exclude from calculated attributes and audience definitions.

\n

\n \n \n \n \n \n \n \n Event Volume Report and value-based pricing

\n

There are differences between the Event Volume Report and your Monthly Credit Usage Report, which is a record of the billable items you are charged for. To learn how billable items are calculated, see Usage metering for value-based pricing (VBP).

\n

The two reports present different views of your data ingestion:
