> Project: Flink

> Components: API / Python
> Reporter: Shuiqiang Chen
> Assignee: Shuiqiang Chen
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.12.0
>
>
> Currently, when users declare a TypeInfo in Python DataStream job it will
> create a Java TypeInfo instance when instantiating. We should make it in a
> lazy style that creates the Java TypeInfo instance only when calling
> TypeInformation.get_java_type_info().
