IDs Overview
Instances of named entities may have instance identifiers (IDs). Some API calls use instance identifiers to create relationships between different instances of named entities. Other API calls associate data with instances of named entities.
An ID may not be reused for different entity instances, unless a previous __itt_id_destroy() call for that ID has been issued.
