------------------------------------

             Summary: Extend TableSource to support nested data
                 Key: FLINK-5280
                 URL: https://issues.apache.org/jira/browse/FLINK-5280
             Project: Flink
          Issue Type: Improvement
          Components: Table API & SQL
    Affects Versions: 1.2.0
            Reporter: Fabian Hueske


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.
