Triggering Savepoints with the Monitoring API

[austin.ce]

Hi there,

I would just like a quick sanity-check: it is possible to start a job with a savepoint from another job, and have the new job save to a new checkpoint directory without overwriting the original checkpoints, correct?

Thank you so much!

Hi Austin,

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

Thanks, vino.
