Relationship History Search Profile

The performance of programmatically searching for relationship instances as they existed in the past.

The Open Metadata Repository Services (OMRS) interface for a metadata repository defines optional methods for searching for relationship instances based on their details in the past, by passing in an asOfTime parameter (captured during the execution of the relationship update profile):

Method Description
findRelationships arbitrarily complex combinations of search criteria including ranges, nested conditions, etc
findRelationshipsByProperty searches for relationship instances based on specific properties with specific values
findRelationshipsByPropertyValue searches for relationship instances based on text that matches any textual property
Assertions
ID Description
repository-relationship-search-history-performance-findRelationships-all-p... Interrogates the technology under test for each relationship type, by calling findRelationships for that type GUID with an asOfTime using the timestamp captured prior to the execution of the relationship update profile. These tests are performed without any explicit sorting of results, and all pages of results are retrieved (the p... portion indicates a specific page number): thereby also exercising the efficiency of the technology under test to consistently cycle through pages of results.
repository-relationship-search-history-performance-findRelationshipsByPropertyValue-exact Repository performs historical search with an exact text value, sorting by oldest creation time, of first page of instances of a type.
repository-relationship-search-history-performance-findRelationshipsByPropertyValue-start Repository performs historical search with a text value 'starts-with', sorting by newest creation time, of first page of instances of a type.
repository-relationship-search-history-performance-findRelationshipsByPropertyValue-contains Repository performs historical search with a text value 'contains', sorting by oldest update time, of first page of instances of a type.
repository-relationship-search-history-performance-findRelationshipsByPropertyValue-end Repository performs historical search with a text value 'ends-with', sorting by newest update time, of first page of instances of a type.
repository-relationship-search-history-performance-findRelationshipsByPropertyValue-regex Repository performs historical search with a regular expression text value, sorting by GUID, of first page of instances of a type.
repository-relationship-search-history-performance-findRelationshipsByProperty-one Repository performs historical search by a single property value, sorting by that property, of first page of instances of a type.
repository-relationship-search-history-performance-findRelationshipsByProperty-all Repository performs historical search by two property values, sorting by the second property, of first page of instances of a type.
repository-relationship-search-history-performance-findRelationshipsByProperty-any Repository performs historical search by two property values, sorting by the second property, of first page of instances of a type.
repository-relationship-search-history-performance-findRelationshipsByProperty-none Repository performs historical search by two property value, sorting by the first property, of first page of instances of a type.

Search variations

When findRelationshipsByProperty is run by the assertions starting with repository-relationship-search-history-performance..., the tests prefer non-string properties (if any exist for the type) given that the findRelationshipsByPropertyValue searches will already heavily exercise string-based queries.
