zentol commented on issue #6910: [FLINK-10490][tests] OperatorSnapshotUtil
should use SavepointV2Seria…
URL: https://github.com/apache/flink/pull/6910#issuecomment-432708555
The code loading the savepoint is aware of previous versions and starts a
migration routine if a v1 savepoint is detected; the savepoint is loaded using
the v1 serializer and migrated before it is passed to the task.
I supposed our migration tests aren't affected since they don't make
structural changes to jobs, which IIRC is the major limitation of the old
format.

> {{OperatorSnapshotUtil}} is used for testing savepoint migration. This
> utility internally still uses {{SavepointV1Serializer}} and I would assume
> that it should use {{SavepointV2Serializer}}. I wonder if that means that
> some newer cases are actually not covered in the migration tests.
