slfan1989 opened a new pull request, #7008:
URL: https://github.com/apache/iceberg/pull/7008
### Background
Flink1.16 `TableSchema` is Deprecated
```
This class has been deprecated as part of FLIP-164.
It has been replaced by two more dedicated classes `Schema` and
`ResolvedSchema`.
Use Schema for declaration in APIs.
ResolvedSchema is offered by the framework after resolution and validation.
```
Some methods have been marked by `Flink` as methods to be deleted, We should
implement our code according to the method recommended by `Flink`.
TypeConversions#fromDataTypeToLegacyInfo
```
/**
* @deprecated Please don't use this method anymore. It will be removed
soon and we should not
* make the removal more painful. Sources and sinks should use the
method available in
* context to convert, within the planner you should use either {@code
InternalTypeInfo} or
* {@code ExternalTypeInfo} depending on the use case.
*/
@Deprecated
public static TypeInformation<?>[] fromDataTypeToLegacyInfo(DataType[]
dataType) {
return Stream.of(dataType)
.map(TypeConversions::fromDataTypeToLegacyInfo)
.toArray(TypeInformation[]::new);
}
```
In This PR, I will use `ResolvedSchema` to replace `TableSchema`.
Modifications Include:
