Relationship Creation Profile

The performance of programmatically creating new relationship instances.

The Open Metadata Repository Services (OMRS) interface for a metadata repository defines optional methods for creating relationship instances:

Method Description
addRelationship adds a new relationship instance, where the technology under test is the home repository for that instance
saveRelationshipReferenceCopy adds (or updates) an existing relationship instance, where the technology under test is not the home repository for that instance
Assertions
ID Description
repository-relationship-creation-performance-addRelationship Invocation of the addRelationship method during the profile (see detailed logic below).
repository-relationship-creation-performance-saveRelationshipReferenceCopy Invocation of the saveRelationshipReferenceCopy method during the profile (see detailed logic below).

For every relationship type supported by the technology under test, this profile invokes each of these methods instancesPerType times.

Example

So, for example, if the technology under test supports 50 relationship types, and the instancesPerType parameter is set to 100, then this profile will create 50 (types) x 100 (instances per type) x 2 (home + non-home methods) = 10 000 relationship instances.

The properties of each of these instances will be fully-populated with:

  • Any string properties containing a value representative of the property name itself (and where unique, they will be made unique through appending a unique sequence)
  • Any non-string properties will be randomly generated, in a simple attempt to represent data that is not entirely uniform

In addition, these tests will record into the Environment profile the totalRelationshipsCreated.
