Entity Creation Profile¶
The performance of programmatically creating new entity instances.
The Open Metadata Repository Services (OMRS) interface for a metadata repository defines optional methods for creating entity instances:
| Method | Description |
|---|---|
addEntity |
adds a new entity instance, where the technology under test is the home repository for that instance |
saveEntityReferenceCopy |
adds (or updates) an existing entity instance, where the technology under test is not the home repository for that instance |
Assertions
| ID | Description |
|---|---|
repository-entity-creation-performance-addEntity |
Invocation of the addEntity method during the profile (see detailed logic below). |
repository-entity-creation-performance-saveEntityReferenceCopy |
Invocation of the saveEntityReferenceCopy method during the profile (see detailed logic below). |
For every entity 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 entity 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 entity 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, such as
qualifiedName, 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 totalEntitiesCreated.
