> 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
