Feifan Wang commented on FLINK-29913:
-------------------------------------
Thanks for your information [~klion26] , I would like to add a case that I
recently thought of a possible problem: Since 1.17, user can trigger checkpoint
with assigned checkpoint type (CONFIGURED,FULL,INCREMENTAL). If user trigger a
FULL checkpoint by rest api, this forces re-upload of snapshot files that have
already been uploaded. Using remote file path based register key is still valid
in this case.
I have submitted a PR, please help to review it [~roman] ,[~klion26] .
