-------------------------------
Summary: Support string representation for types like array
Key: FLINK-10120
URL: https://issues.apache.org/jira/browse/FLINK-10120
Project: Flink
Issue Type: Improvement
Components: Type Serialization System
Reporter: buptljy
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.
