Atlas Entity Version does not update after entity update

Old Entity

{ "entity": { "attributes": { "createTime": 0, "description": "", "locationUri": null, "name": "BCaLYKStWE", "owner": null, "randomTable": null }, "classifications": [ ], "createdBy": "admin", "createTime": 1527764632465, "guid": "e57a85ed-bdc9-4069-96a3-401b7c0a1365", "status": "ACTIVE", "typeName": "hive_db_v2", "updatedBy": "admin", "updateTime": 1527764668060, "version": 0 }, "referredEntities": { } }

New Entity

{ "referredEntities": {}, "entity": { "typeName": "hive_db_v2", "attributes": { "owner": null, "randomTable": null, "createTime": 0, "name": "BCaLYKStWE", "description": "", "locationUri": "" }, "guid": "e57a85ed-bdc9-4069-96a3-401b7c0a1365", "status": "ACTIVE", "createdBy": "admin", "updatedBy": "admin", "createTime": 1527764632465, "updateTime": 1527764668060, "version": 0, "classifications": [] } }

Note that version remains 0 even after the update. Am I missing something?

Your observation is valid.

The version number is something related to the model (schema, definition is present in addons/models) of the entity and not the version of the entity itself.

Also, as of now, we don't have logic for dealing with version changes to schema.

In short, version field is not of much consequence right now.

@Ashutosh Mestry How about typeVersion, I don't see that being much useful either? (Refer StructTypeDefinition.java).

P.S. It would be really nice to have a version and typeversion implementation that updates itself to trace back the evolution.
