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

             Summary: v2 storage(for parallel scan) backward compatibility with v1 storage
                 Key: KYLIN-1126
                 URL: https://issues.apache.org/jira/browse/KYLIN-1126
             Project: Kylin
          Issue Type: Improvement
            Reporter: hongbin ma
            Assignee: hongbin ma


As KYLIN-942 introduced a new storage format with shard put at the beginning of each rowkey(we call it v2 storage), cubes built with previous versions of job engines will no longer be compatible with current query engine. Need to refactor job engine& query engine to support both version of cube storage.
