[jira] [Commented] (FLINK-6764) Deduplicate stateless TypeSerializers when serializing composite TypeSerializers

["Tzu-Li (Gordon) Tai (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-6764?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16325062#comment-16325062 ] 

Tzu-Li (Gordon) Tai commented on FLINK-6764:
--------------------------------------------

It seems like we forgot completely about adding this to 1.4.0.

Since the previous conclusion was that we do not want to change serialization formats across minor releases, we can't include this for 1.4.1.
We should make sure we include this change in 1.5.0 (as soon as possible), as serialization formats will affect us a long way ahead.

Marking this as a blocker for 1.5.0.

> Composite type serializer, such as the {{PojoSerializer}}, could be improved by deduplicating stateless {{TypeSerializer}} when being serialized. This would decrease their serialization size.
