Relationship Re-Identify Profile

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

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

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

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

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


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