Session: How to Get Entity Change-Vector

• The change-vector reflects the cluster-wide point in time in which a change occured, and includes the unique database ID, node identifier, and document Etag in the specific node.
• When a document is downloaded from the server, it contains various metadata information.
  E.g. ID or current change-vector.
• The current change-vector is stored within the session metadata and is available for each entity using the getChangeVectorFor method from the advanced session operations.

Syntax

<T> String getChangeVectorFor(T instance)

Example

Employee employee = session.load(Employee.class, "employees/1-A");
String changeVector = session.advanced().getChangeVectorFor(employee);
