Jark Wu created FLINK-14645: ------------------------------- Summary: Data types defined in DDL will lose precision and nullability when converting to properties Key: FLINK-14645 URL: https://issues.apache.org/jira/browse/FLINK-14645 Project: Flink Issue Type: Sub-task Components: Table SQL / API Reporter: Jark Wu Fix For: 1.10.0
Currently, data types defined in DDL will be converted to {{TypeInformation}} and use {{TypeStringUtils}} to serialize/deserialize which will lose the precision and nullablitiy information. We can use {{LogicalType#asSerializableString}} and {{LogicalTypeParser}} to serialize/deserialize data types which keeps all the information. But we need to figure out how to keep compability with previous versions. -- This message was sent by Atlassian Jira (v8.3.4#803005)
