[jira] [Created] (ATLAS-1404) Improve lineage performance with query filters using only GUID

Suma Shivaprasad created ATLAS-1404:
---------------------------------------

             Summary: Improve lineage performance with query filters using only GUID
                 Key: ATLAS-1404
                 URL: https://issues.apache.org/jira/browse/ATLAS-1404
             Project: Atlas
          Issue Type: Bug
    Affects Versions: 0.8-incubating
            Reporter: Suma Shivaprasad
            Assignee: Suma Shivaprasad
             Fix For: 0.8-incubating


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
