------------------------------------
Summary: Add a converter from TypeInformation to DataType
Key: FLINK-20862
URL: https://issues.apache.org/jira/browse/FLINK-20862
Project: Flink
Issue Type: Sub-task
Components: Table SQL / API
Reporter: Timo Walther
Assignee: Timo Walther
Implement a new TypeInfoDataTypeConverter that will no longer produce
LegacyTypeInformationType.
As mentioned in the FLIP:
- All types from DataStream API should be supported by this converter.
- TupleTypeInfoBase will be translated into a proper RowType or StructuredType.
- BigDecimals will be converted to DECIMAL(38,18) by default.
- Composite types (tuples, POJOs, rows) will be flattened by default if they
are used as top-level records (similar to the old behavior).
- The order of POJO field's is determined by the DataTypeExtractor and must not
be defined manually anymore.
- GenericTypeInfo is converted to RawType immediately by considering the
current configuration.
- A DataStream that originated from Table API will keep its DataType
information due to ExternalTypeInfo implementing DataTypeQueryable.
