[jira] [Updated] (FLINK-28636) Add utility to test POJO compliance
[ https://issues.apache.org/jira/browse/FLINK-28636?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Chesnay Schepler updated FLINK-28636:
-------------------------------------
Description:
Users should be encouraged to eagerly verify that their POJOs satisfy all the requirements that Flink imposes, however we provide no convenient way to test that.
They currently have to resort to something like below, which isn't obvious at all:
{code:java}
TypeSerializer<Event> eventSerializer =
TypeInformation.of(Event.class).createSerializer(new ExecutionConfig());
assertThat(eventSerializer).isInstanceOf(PojoSerializer.class);{code}
