Delete Entities by Entity Type

Learn how to delete all entities of a specified type from a tenant.

This Delete entities by entity type operation deletes all entities of a specified type from a tenant. Before you run this task, run the Cassandra Es Consistency Task to ensure that the Elasticsearch storage is in a consistent state with the main data storage. For more information, see topic Cassandra Es Consistency Task.

Note: The Delete entities by entity type task does not wait for all events to be processed. Therefore, after this task is executed, it is possible that some of the entities are available when you search for it. You have to wait for some time before the Elastic Search is consistent with the main data storage.

Request

Query	entityType	Yes	The entity type name. All entities of the specified type are deleted.
Query	mode	No	An optional parameter indicating whether entities of the specified entity type are completely removed from the system or the entities are only flagged as deleted.
