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

             Summary: Convert CharSequence to String when registering / converting a Table
                 Key: FLINK-8179
                 URL: https://issues.apache.org/jira/browse/FLINK-8179
             Project: Flink
          Issue Type: Improvement
          Components: Table API & SQL
    Affects Versions: 1.5.0
            Reporter: Fabian Hueske


Avro objects store text values as `java.lang.CharSequence`. Right now, these fields are treated as `ANY` type by Calcite (`GenericType` by Flink). So, importing a `DataStream` or `DataSet` of Avro objects results in Table where the text values cannot be used as String fields.

We should convert `CharSequence` fields to `String` when importing / converting to a Table.
