> StreamTableEnvironment.toAppendStream fails with Decimal types
> --------------------------------------------------------------
>
> Key: FLINK-16277
> URL: https://issues.apache.org/jira/browse/FLINK-16277
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / API
> Affects Versions: 1.10.0
> Reporter: Benoît Paris
> Priority: Minor
> Labels: auto-deprioritized-major
> Attachments: DecimalType 38 18 Logical - stacktrace.txt,
> flink-test-schema-update.zip
>
>
> The following fails when there is a Decimal type in the underlying
> TableSource:
>
> {code:java}
> DataStream<Row> appendStream = tEnv.toAppendStream(
> asTable,
> asTable.getSchema().toRowType()
> );{code}
> Yielding the following error:
>
> ValidationException: Type ROW<`y` DECIMAL(38, 18)> of table field 'payload'
> does not match with the physical type ROW<`y` LEGACY('DECIMAL', 'DECIMAL')>
> of the 'payload' field of the TableSource return type
> ----
>
> Remarks:
> * toAppendStream is not ready for the new type system, does not accept the
> new DataTypes
> * The LegacyTypeInformationType transition type hinders things. Replacing it
> with the new DataTypes.DECIMAL type makes things work.
> * flink-json is not ready for the new type system, does not give the new
> DataTypes
>
> Workaround: reprocess TypeConversions.fromLegacyInfoToDataType's output to
> replace LegacyTypeInformationType types when they are of DECIMAL typeroot
> with the new types.
>
> Included is reproduction and workaround (activated by line 127) code, with
> java + pom + stacktrace files.
