[jira] [Commented] (FLINK-15436) Add a hook of deserialized for
pojo state object.
[ https://issues.apache.org/jira/browse/FLINK-15436?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17006682#comment-17006682 ]
Yun Tang commented on FLINK-15436:
----------------------------------
[~xiemeilong], Flink would avoid to use java serialization during state serialize. If the {{RuleEvaluator}} did not extend {{Serializable}} interface, you could provide your customized serializer instead of default pojo serializer to (de)serialize that. As I said above, the time to deserialize class is not the same for different state backends.
