-------------------------------
Summary: Throw exceptions for the data types which are not
currently supported
Key: FLINK-16606
URL: https://issues.apache.org/jira/browse/FLINK-16606
Project: Flink
Issue Type: Improvement
Components: API / Python
Affects Versions: 1.10.0
Reporter: Dian Fu
Assignee: Dian Fu
Fix For: 1.10.1, 1.11.0
Currently, there are still cases where a data type isn't supported as the
Python data type will be firstly converted to TypeInformation which will lose a
few information, e.g,
- the precision for TimeType could only be 0
- the length for VarBinaryType/VarCharType could only be 0x7fffffff
- the precision/scale for DecimalType could only be 38/18
- the precision for TimestampType/LocalZonedTimestampType could only be 3
- the resolution for DayTimeIntervalType could only be `SECOND` and the
fractionalPrecision could only be 3
- the resolution for YearMonthIntervalType could only be `MONTH` and the
`yearPrecision` could only be 2
- the CharType/BinaryType/ZonedTimestampType is not supported
We should throw exceptions for the cases not supported.
