Arvind Prabhakar commented on HIVE-365:
---------------------------------------
For the table "nested" as defined above, a row that contains the following data:
[ [1,2,3],[10,20,30] ], { {foo:{1:1} }, {bar:{2,2} } }
would be represented as:
1 \003 2 \003 3 \002 10 \003 20 \003 30 \001 foo \003 1 \004 1 \002 \bar \003 2
\004 2
note: spaces added for readability
> Create Table to support multiple levels of delimiters

> Key: HIVE-365
> URL: https://issues.apache.org/jira/browse/HIVE-365
> Project: Hadoop Hive
> Issue Type: New Feature
> Reporter: Zheng Shao
>
> From HIVE-337, the SerDe layer now supports multiple-levels of delimiters,
> for the purpose of supporting nested map/array/struct.
> Array(the same as List) and struct consume a single level of separator, and
> Map consumes 2 levels.
> DDL (Create Table) needs to allow users to specify multiple levels of
> delimiters in order to take the advantage of this new feature.
