Entity Change Event V1

Event Type

EntityChangeEvent_v1

Overview

This Event is emitted when certain changes are made to an entity (dataset, dashboard, chart, etc) on DataHub.

Event Structure

Entity Change Events are generated in a variety of circumstances, but share a common set of fields.

Common Fields

Name	Type	Description	Optional
entityUrn	String	The unique identifier for the Entity being changed. For example, a Dataset's urn.	False
entityType	String	The type of the entity being changed. Supported values include dataset, chart, dashboard, dataFlow (Pipeline), dataJob (Task), domain, tag, glossaryTerm, corpGroup, & corpUser.	False
category	String	The category of the change, related to the kind of operation that was performed. Examples include TAG, GLOSSARY_TERM, DOMAIN, LIFECYCLE, and more.	False
operation	String	The operation being performed on the entity given the category. For example, ADD ,REMOVE, MODIFY. For the set of valid operations, see the full catalog below.	False
modifier	String	The modifier that has been applied to the entity. The value depends on the category. An example includes the URN of a tag being applied to a Dataset or Schema Field.	True
parameters	Dict	Additional key-value parameters used to provide specific context. The precise contents depends on the category + operation of the event. See the catalog below for a full summary of the combinations.	True
auditStamp.actor	String	The urn of the actor who triggered the change.	False
auditStamp.time	Number	The timestamp in milliseconds corresponding to the event.	False
