--------------------------------
Summary: Window related serailizer should not return 0 as its
serialized length
Key: FLINK-24210
URL: https://issues.apache.org/jira/browse/FLINK-24210
Project: Flink
Issue Type: Bug
Components: API / Type Serialization System, Runtime / State Backends
Reporter: Yun Tang
TimeWindow serializer return 0 as its length for serialization, this is
certatinately not correct.
{code:java}
public static class Serializer extends TypeSerializerSingleton<TimeWindow> {
....
@Override
public int getLength() {
return 0;
}
}
{code}
Current namespace serializer in state backend does not depends on this
interface so that no obvious bug has ever reported.
Moreover, this bug also occurs in other window related serializer.
