>                 Key: FLINK-7389
>                 URL: https://issues.apache.org/jira/browse/FLINK-7389
>             Project: Flink
>          Issue Type: Sub-task
>          Components: Table API & SQL
>            Reporter: Timo Walther
>
> The PushProjector class is copied from Apache Calcite except that it does not 
> automatically name the field using the name of the operators as the Table API 
> rejects special characters like '-' in the field names.
> We need to find a solution without copying Calcite classes.
