> 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.
