------------------------------------

             Summary: Separating storage devices/directories and workspace devices/directories
                 Key: ASTERIXDB-1848
                 URL: https://issues.apache.org/jira/browse/ASTERIXDB-1848
             Project: Apache AsterixDB
          Issue Type: Improvement
            Reporter: Yingyi Bu
            Assignee: Yingyi Bu


We need to separate the devices/directories for operator workspaces and devices/directories
for the permanent data storage.

A motivation scenario is AWS. There're two kinds of AWS storage:
-- instance level storage, i.e., local storage.  Can be lost if a failure happens and are
recommended for the temporary usage, caching, etc.
-- EBS.  Have better persistency properties.
