buptljy updated FLINK-10120:
----------------------------
Description:
In TypeStringUtils.readTypeInfo:
{code:java}
case _: BasicArrayTypeInfo[_, _] | _: ObjectArrayTypeInfo[_, _] |
_: PrimitiveArrayTypeInfo[_] =>
throw new TableException("A string representation for array types is not
supported yet.")
{code}
This exception makes us unable to create a table schema or format schema with a
array type field.
I'm not sure whether this is an improvement or not, because you throw an
exception explicitly here.
was:
Now we have to use row type to replace array type when we want to create a
table schema or format schema with nested types. For example, we have to use
{code:java}
Types.ROW(
new String[]{"a", "b", "c"},
new TypeInformation[]{Types.STRING(), Types.INT(), Types.ROW(
new String[]{"a", "b", "c"},
new TypeInformation[]{Types.STRING(),
Types.STRING(),Types.STRING()})}
{code}
instead of
{code:java}
Types.ROW(
new String[]{"a", "b", "c"},
new TypeInformation[]{Types.STRING(), Types.INT(),
BasicArrayTypeInfo.STRING_TYPE_INFO})
{code}
because the program will fail in TypeStringUtils.readTypeInfo.
