Hi All,

I am working on supporting complex type map columns. Please find below the
scope for the same.

*Scope:*
1. Create Table DDL support for complex map type.
1. Support loading of data for complex map type column [SDK, DataLoad DDL].
2. Design to consider n level nested support for map values and keys as
primitive types similar to Hive.
3. Support querying complex type map columns.
5. Support all datatypes in map complex type values includng struct and
array.
6. Describe formatted support to display the complex map type column.
7. Support configurable delimeters for key and value separator and a
separator for each map entry.

Please feel free to provide your comments and suggestions. I am working on
the design document and will upload soon.
