[jira] [Updated] (ATLAS-2092) Failures following concurrent updates

     [ https://issues.apache.org/jira/browse/ATLAS-2092?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Graham Wallis updated ATLAS-2092:
---------------------------------
    Description: There is a race condition that causes duplication of schema vertices as a result of concurrent graph updates. This in turn leads to failure of queries that specify a type such as an edge label used in an attribute that references another entity. This problem is known to affect Atlas entity refs – which create graph edges that use edge label schema vertices. It is likely that it also affects other types in Atlas.
