> Linage currently queries by superTypeName + guid combinations for which a composite index
does not exist and index exists for typeName or guid alone. Subsequent filters are getting
applied on typename query results which take a long time to finish. Hence rewriting these
queries to use the GUID alone for querying and then apply the supertype checks once the entity
definition is retrieved from the repository using its type
