Jeff Hammerbacher commented on HIVE-1540:
-----------------------------------------
We've got an increasing number of customers using Avro's serialization format
for working with data in Hadoop, and that's where our nested data structures
come from. Any design which could incorporate a serialization framework like
Avro would be of interest to me.
> Read-only, columnar data file for nested data structures

> 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.
