Yuan Mei updated FLINK-23441:
-----------------------------
Description:
CheckpointOptions contain many fields that are not related to the backend
snapshot (materialization in changelog):
alignment type, alignedCheckpointTimeout, and even
CheckpointStorageLocationReference
(the location is provided by/included in the #StreamFactory# already, we do not
use CheckpointStorageLocationReference in away place in snapshotting.
=================================
In the future, if we want to separate checkpointing away from materialization
(conceptually, they are indeed two different pieces as well), we do not need to
provide such CheckpointOptions for each snapshotting.
> Remove CheckpointOptions Argument away from Snapshotable#snapshot
