Hi Austin,

It seems that your scene is very suitable for a usage scenario of Fli= nk's Savepoint: A/B Test (or upgrade application). Yes, Flink can suppo= rt this requirement, but you should understand that these two jobs will be = subject to certain restrictions. For more information, please refer to Offi= cial documentation.[1]

Thanks, vino.

Hi there,

I would just like a quick sanity-chec= k: it is possible to start a job with a savepoint from another job, and hav= e the new job save to a new checkpoint directory without overwriting the or= iginal checkpoints, correct?

Thank you so much= !
Austin
