BigQuery Exports

​

Overview

BigQuery is a fully managed, serverless data warehouse available on the Google Cloud Platform (GCP). It allows you to perform complex analytics on terabytes of data in real time without managing infrastructure.

​

How Does MoEngage Work with BigQuery?

The MoEngage and BigQuery integration directly transfers user and event data to Google BigQuery for advanced analytics.

​

Integration

To create a BigQuery connection, refer to Google BigQuery.

​

Export Events from MoEngage to BigQuery

​

Step 1: Ensure Your User’s Assigned Role Has Required Permissions

To successfully set up and execute a BigQuery export, your service account or user must have the following permissions based on the action being performed:

• To Create a Connection: To establish a new BigQuery connection within the MoEngage App Marketplace, the user must have the BigQuery Data Viewer and BigQuery Job User roles. This allows MoEngage to validate the project and dataset details. For more information, refer here.
• To Perform Exports: To execute the actual data transfer, your service account must be assigned the BigQuery Data Editor role. This grants MoEngage the necessary permissions to read and write data to your specific BigQuery tables.

​

Step 2: Add a New BigQuery Export in the MoEngage App Marketplace

To add a new BigQuery export, perform the following steps:

1. On the left navigation menu in the MoEngage UI, click App marketplace.
2. On the App Marketplace page, search for BigQuery.
3. Click the Google BigQuery tile.
4. On the Google BigQuery page, go to the Integrate tab and click +Add Export.
5. Enter the following details:

   Field	Required	Description
   Export name	Yes	Type a name for the BigQuery export. Ensure your export name contains at least three characters.
   BigQuery connection	Yes	Select your BigQuery connection.
   Dataset ID	Yes	Select the specific dataset in BigQuery where your data will be exported.
   Table name	Optional	Enter the name for the export table. If left blank, MoEngage creates a name for you with the prefix moe_events. Note: To avoid errors, allow MoEngage to automatically create this table.
   User Properties	Optional	Select the specific user properties you want to include in the export.
   Select events	Yes	Select the events to export to BigQuery. You can choose to export all events, including existing and new events coming into MoEngage, or manually select specific events to export.

6. Click Save export.

Now, MoEngage populates the newly created table with events every hour.

​

Export Process and Frequency

After you save the export, MoEngage creates a destination table in your dataset. New event data is then appended to this same table at hourly intervals: Initial action: MoEngage creates the table when the first export is triggered. Recurring action: MoEngage adds (appends) data to the same table every hour.

​

Sample Table Structure

If you do not specify a table name in the export configuration, MoEngage creates a single table in your dataset using the following format:
moe_events_<table_creation_timestamp> The overall structure of the table remains fixed for all event types. Any new user property or event attribute that is exported will be included in the user_attributes or event_attributes column, respectively. All events are consolidated in a single table containing necessary information, such as event names and event times, for easy analysis:

​

Export Failure Policy

MoEngage pauses an export that keeps failing. While it is paused, MoEngage collects the events the export would have delivered, and you replay them after you fix the problem.

​

When MoEngage Pauses an Export

Exports to BigQuery run hourly. MoEngage will retry an export multiple times before marking it as failed. The export will be paused after 3 consecutive scheduled export failures. When MoEngage pauses an export, it alerts you and shows the export as Paused on the App Marketplace.

​

What Happens While an Export Is Paused

MoEngage collects the events the export would have delivered and keeps only the most recent 7 days. If the export stays paused for longer than a week, MoEngage drops the oldest days as newer ones come in. If an export pauses more than once before you replay, MoEngage combines the data from all those pauses, provided it falls within the 7-day window.

​

Resume an Export

​

Find the Failure Reason

On the App Marketplace, click the Integrate tab, and then hover over the Paused label on the export. MoEngage names the reason for the failure, such as a missing write permission on the destination table, and tells you how to fix it.

​

Enable the Export

Fix the cause at your end, and then turn on Export status for the export. Do this as soon as you can, because the 7-day window keeps moving while the export stays paused. When you enable the export, MoEngage stops collecting and sets aside what it has: the last 7 days of paused data, or all of it if the pause was shorter. This is the data you can replay. It stays fixed from then on, and does not reduce further even if you wait to replay it.

​

Replay Paused Data

​

Request a Replay

MoEngage saves the data it collected while the export was paused. An export with data waiting shows a Replay available label on the Integrate tab. To replay, perform the following steps:

1. Hover over the Replay available label, or open the kebab menu on the export.
2. Click Replay paused data.
3. In the Replay paused data dialog box, click Confirm.

A replay sends everything MoEngage collected while the export was paused. MoEngage appends the data to the destination table. You can replay at any time until 30 days from the date the oldest paused data was collected. After that, the data is no longer available.

​

Replay Results

When the replay finishes, MoEngage emails the user who requested it with one of the following results: You can run only one replay per export at a time.

​

Avoid Duplicate Data

Every replay sends the whole collection again, because MoEngage does not deduplicate. If you replay more than once, deduplicate at your end on the event_uuid field, which is unique for each event. For the fields in the export, refer to the Data Export Glossary.

​

Export Paused Alerts

MoEngage alerts you when it pauses an export, so you can fix the issue and replay the data collected while the export was paused. MoEngage subscribes workspace admins to the Data Exports system alert by default, and adds the user who creates or updates an export. To subscribe or unsubscribe anyone else, go to the Alert Management page. Subscribing or unsubscribing changes notifications only for that person, and does not affect anyone else’s subscription.
