Hi everyone,
I just published a new FLIP to introduce operator state compression (1).
This feature is pretty straightforward to implement, so a PR is already
under review (2) but it appeared during the review that to be able to
insure backward compatibility of the operator state snapshots, we needed
to modify the snapshot format hence the FLIP.
Please tell me if you have any thoughts about it.

Best,
