Session: How to Get Entity Change-Vector

The change-vector reflects the cluster-wide point in time where something happened. It includes the unique database ID, node identifier, and the Etag of the document in the specific node. When a document is downloaded from the server, it contains various metadata information e.g. ID or current change-vector. Current change-vector is stored within the metadata in session and is available for each entity using the getChangeVectorFor() method from the advanced session operations.

Syntax

session.advanced.getChangeVectorFor(entity);

Example

const employee = await session.load("employees/1-A");
const changeVector = session.advanced.getChangeVectorFor(employee);
