Automatic Unmerge Task

Learn about the Automatic Unmerge API

Real-time profiles' automatic unmerge happens exclusively when their source attributes are updated. If your profiles haven't been updated recently, they might need to be unmerged based on your current automatic match rules. Otherwise, they'll remain merged, unless you take action. Run the batchUnmergeEntities task when you want to ensure entities that no longer match are automatically unmerged. This line of action is important, if you made any of these changes after you loaded your data:
  • Added, deleted, or edited match rules
  • Edited survivorship rules for any attributes included in match rules
Note: You can run the task to test whether the entities are subject to unmerge and reports the number of such entities, even if Automatic Unmerge is disabled at the entity type level. You can run the task with readOnly=true mode on the tenant, and the task tests which entities should be unmerged. The mode readOnly=false works as earlier only on the entity type where Automatic unmerge is enabled. For more information, see topic Enable automatic unmerge on the tenant configuration.

Request

Tenant admin role is required:

POST {ApplicationURL}/api/{tenantId}/batchUnmergeEntities
Parameter Required Default Value Description
uriList No

List of entity URIs candidate to unmerge (for example: 00005KL, 00009ab).

entityType No The entityType on which the task is to be run. If you don't specify it, the task will run on whole tenant.
readOnly No trueIf true, only tests candidate entities for unmerge. It doesn't commit changes.
updatedSince No 0

Only entities with updatedTime ≥ updatedSince will be unmerged.

updatedTillNo0

Only entities with updatedTime < updatedTill will be unmerged.

distributedNofalseIf set to true, the task runs in distributed mode (refer to Distributed Mode).
taskPartsCountNo2If you set distributed=true, you can specify the number of parts in which you want to execute this task.
Note: This parameter is used only in distributed mode distributed=true, otherwise it is ignored.
entitiesLimitNo The number of entities to be processed by the task.

You can retrieve detailed information by getting the task by its ID.
