Note: The data deletion function is supported in privatization v4.5.0 and above. If you need to delete in other versions, please contact your customer success manager; since privatization v5.2.0, routine deletion tasks are supported.

The data deletion function is used to clean up the historical behavior event data that has been imported in the Datafinder. The range of data that supports deletion is:

• In-app, history all event data for a specific date range
• In-app, history partial event data for a specific date range (specific event name)

This function is not suitable for deleting data of a specific user. If necessary, please refer to: User Data Deletion Instructions

1. The data deletion operation is irreversible and cannot be restored once deleted.
2. Frequent data deletion may affect the data import progress, please proceed with caution
3. Deleting historical event data may have the following effects:
   (1) For dashboards, routine grouping tasks, etc. that have used deleted data, query results will be affected
   (2) Behavioral event data may be used by multiple platforms, including but not limited to: user growth analysis platform, customer data platform, A/B experimental intelligence engine, Datawind, advertising monitoring platform, growth marketing platform, etc. Please confirm that the deletion of data does not affect the use of the above platform users

• The deletion operation is completed by the background task, and the deleted data cannot be queried on the DataFinder after the operation.
• Currently, data can only be deleted by day, not by hour or minute. After the data deletion task is created, the deletion operation will be performed in the early morning of the next day, depending on the actual scheduling of all data deletion tasks.
• There is no maximum execution concurrency limit for the deletion task, and the deletion operation should be carried out during the low peak period of the business to reduce the impact on the business.
• It is necessary to obtain detailed confirmation before operation and to clearly understand the possible risks. The deletion operation carries certain risks, which may result in query errors or a small amount of data loss.
• If you select an event other than any event to delete, the data deletion cannot be queried, but it cannot free up disk space.

Operation permission #

The data deletion operation is limited to the group/project administrator operation, and other members cannot perform the deletion operation.

Create a data deletion task: single task #

Create task #

1. After logging in and entering the DataFinder console, click the top navigation bar, Data Management > Data Governance > Data Delete, click "New Delete Task", and select "New Single Task".

2. Fill in the data range that needs to be deleted in the pop-up box.
   
   Configuration instructions:

   Parameter	Configuration instructions
   app name	Default current application, each data deletion task can only select one application name.
   date range	A single task can delete data for up to 30 consecutive days, and data for future dates cannot be deleted.
   event name	This item is optional. Default all events if unchecked, that is, all behavioral event data for the date range is deleted. If an event name is selected, only specific event data is deleted, and up to 50 events are selected.

3. Please be sure to read the data deletion risk notice carefully, and click "Confirm Deletion" after confirming that the data deletion application name, date range, event range, and estimated number of deleted data pieces meet your expectations; otherwise, please click "Cancel" to return to modify.
   

Task notification #

Since data deletion will affect the use of all members, and cannot be replenished after deletion, the system will automatically push a message notification when the following situations occur.

Withdraw task #

Since deleting a task may affect the normal data import progress, the task will be set to be executed in the idle time of the system, and the administrator can withdraw the task before it is officially executed. Once the task has started, it cannot be withdrawn.

Operation log #

You can click "operation log" to view the task log record, and the log will be preserved forever.

Create a data deletion task: a routine task #

Create task #

1. After logging in and entering the DataFinder console, click the top navigation bar, Data Management > Data Governance > Data Delete, click "New Delete Task", and select "New Routine Task".

2. Fill in the data range that needs to be deleted in the pop-up box.
   
   Configuration instructions:

   Parameter	Configuration instructions
   app name	Default current application, each data deletion task can only select one application name.
   event name	This item is optional. Default all events if unchecked, that is, all behavioral event data for the date range is deleted. If an event name is selected, only specific event data is deleted, and up to 50 events are selected.
   routine cycle	The current support configuration routine deletes specified data weekly or daily. Daily: When data is routinely deleted every day, only one day of data can be deleted. Weekly: When data is routinely deleted every week, only 1 week (7 days) of data can be deleted, and data can be deleted by specifying the week of the week.
   data retention duration	After setting the data retention period, DataFinder will retain the data for you for a period of time before deleting it, based on the routine deletion period you set. For example, if you set the data deletion routine to be "daily" and the data is retained for 3 days, DataFinder will retain the data for 3 days before deleting it. That is, on January 4, the data on January 1 will be deleted.

Task notification #

Since data deletion will affect the use of all members, and cannot be replenished after deletion, the system will automatically push a message notification when the following situations occur.

Manual start and stop tasks #

After the routine task is created, the task is started by default, and you can manually turn off/enable the routine data deletion task in the routine task list.

Operation log & Failure rerun #

• You can click "operation log" to view the task log record, and the log will be preserved forever.
  
• If a routine task fails in a certain cycle, you need to recreate a single task and delete the corresponding data again.

Q1 How can I confirm whether the data has been deleted successfully? #

When the task is completed, all members of the project will receive an email message notification. At this time, you can check in the "Event Analysis" module whether the amount of events on this date has decreased. If there is no reduction, please resubmit the task and delete it again.

Q2 Why is the data still queried in the system after the data is deleted? #

After the data is deleted, the system may still receive historical data reports and continue to build, so even if the historical data is deleted, it will not affect the import of new data.

Q3 Can the administrator grant operation permissions to other members? #

No, it needs to be operated by the group or project administrator.

Q4 What should I do if the task execution fails? #

It is recommended that you resubmit the task for deletion. If it fails again, please contact your Customer Success Manager.

Q5 Can I backtrack after data deletion? #

No, once the data is deleted, it cannot be replenished. Please be sure to operate with caution.

Q6 When does the data deletion task start and is there a concurrency limit? #

After the data deletion task is created, the deletion operation will be performed in the early morning of the next day. The specific time depends on the actual scheduling of all data deletion tasks, and there is no concurrency limit.
