Read-only, columnar data file for nested data structures
--------------------------------------------------------

                 Key: HIVE-1540
                 URL: https://issues.apache.org/jira/browse/HIVE-1540
             Project: Hadoop Hive
          Issue Type: New Feature
            Reporter: Jeff Hammerbacher


RCFile is a great start on an optimized layout for working with structured data with Hive.
Given that Hive's data model supports nested lists and maps, and taking inspiration from the
recent work by Google on Dremel, it may be useful for the Hive community to think about how
to improve the RCFile format for nested data structures.
