Subject [jira] [Commented] (ATLAS-129) Atlas cannot use Cassandra as the storage backend.
Date Mon, 31 Aug 2015 03:17:45 GMT

    [ https://issues.apache.org/jira/browse/ATLAS-129?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14721917#comment-14721917
] 

Shwetha G S commented on ATLAS-129:
-----------------------------------

Atlas provides wrapper APIs to access graphs. Use <atlas endpoint>/api/atlas/graph/vertices
instead

> Atlas cannot use Cassandra as the storage backend.
