[jira] [Updated] (FLINK-6554) CompatibilityResult should contain a
notCompatible() option
[ https://issues.apache.org/jira/browse/FLINK-6554?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Chesnay Schepler updated FLINK-6554:
------------------------------------
Description:
The {{CompatibilityResult}} allows a {{TypeSerializer}} to specify whether it is compatible based on the given {{TypeSerializerConfigSnapshot}}.
As it stands the only options are {{compatible}} and {{requiresMigration}}. We should allow serializers to also notify the system of an incompatibility which should then fail the job.
This would for example be required when a serializer provides an upgrade path version1 -> version2 -> version3, but not directly from version1 -> version3. Currently, the serializer would either have to contain logic to upgrade from every single previous version or simply throw an exception on it's own.
