Description

The TableSource interface does currently only support the definition of flat rows.

However, there are several storage formats for nested data that should be supported such as Avro, Json, Parquet, and Orc. The Table API and SQL can also natively handle nested rows.

The TableSource interface and the code to register table sources in Calcite's schema need to be extended to support nested data.
