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

string GetChangeVectorFor<T>(T instance);

Example

Employee employee = session.Load<Employee>("employees/1-A");
string changeVector = session.Advanced.GetChangeVectorFor(employee);
