Sihua Zhou updated FLINK-8753:
------------------------------
    Description: 
Right now, savepoint goes through the full checkpoint path, take a savepoint 
could be slowly. In our production, for some long term job it often costs more 
than 10min to complete a savepoint which is unacceptable for a real time job, 
so we have to turn back to use the externalized checkpoint instead currently. 
But the externalized  checkpoint has a time interval (checkpoint interval) 
between the last time. So I proposal to introduce the increment savepoint which 
goes through the increment checkpoint path.

Any advice would be appreciated!
