Entity Re-Identify Profile

The performance of programmatically changing the GUID of an existing entity instance.

The Open Metadata Repository Services (OMRS) interface for a metadata repository defines an optional method for changing the GUID of entity instances:

Method Description
reIdentifyEntity changes the GUID of an existing entity
ID Description
repository-entity-re-identify-performance-reIdentifyEntity See (2) in detailed logic below.

For every entity type supported by the technology under test, this profile does the following (in order):

  1. Searches for instancesPerType homed entity GUIDs of that type. (This uses findEntitiesByProperty with a condition on metadataCollectionId and its performance is recorded as part of the entity search profile.)
  2. For each of these entity GUIDs, reIdentifyEntity is called to change the GUID of the entity to a new random GUID.


So, for example, if the technology under test supports 50 entity types, and the instancesPerType parameter is set to 100, then this profile will re-identify 50 (types) x 100 (instances per type) = 5000 entities. (And it will run findEntitiesByProperty 50 times.)
