DuckDB limited support?

[thadguidry]

DuckDB is a fast analytical OLAP database and used heavily in research and the scientific community where the needs for sharing via REST interfaces has become more important. I'm not 100% sure if the Arrow Vector streaming where DuckDB also offers Arrow streaming with batches, would be useful or not, so we might initially skip supporting that. However, the Appender class is very useful for bulk import and completely avoids needing SQL.

DuckDB can be supported easily in full glory because it has JDBC driver. All features are available with this JDBC type 4 driver
