Hi Konstantin,
Thank you for your feedback. You’re right that this part belongs to the
savepoint desrializing.
This is an old issue which should be resolve before 1.3 version according
to the comments. Anyway, I’m going to keep following this.
Best Regards,
Jiayi Liao

Subject:Re: Add relative path support in Savepoint Connector
Hi Jiayi, I think, this is not an issue with the State Processor API
specifically, but with savepoints in general. The _metadata file of a savepoint
uses absolute path references. There is a pretty old Jira ticket, which already
mentioned this limitation [1]. Stefan (cc) might know more about any ongoing
development in that direction and might have an idea about the effort of making
savepoints relocatable. Best, Konstantin [1]

relative path support in Savepoint Connector Hi all, Firstly I appreciate
Gordon and Seth’s effort on this feature, which is really helpful to our
production use. Like you mentioned in the FLINK-12047, one of the production
uses is that we use the existing state to derive new state. However, since the
state handle is using the absolute path to get the input stream, we need to
directly operate the state in production environment, which is not an
anxiety-reducing situation, at least for me. So I wonder if we can add the
relative path support in this module because the files are persisted in a
directory after we take a savepoint, which makes it achievable. I’m not sure
whether my scenario is a common case or not, but I think I can give my
contributions if you all are okay about this. Best Regards, Jiayi Liao
