Re: How to recovery from last count when using CUMULATE window after restart flink-sql job?

2021-05-09 Thread Jark Wu
Hi,

When restarting a Flink job, Flink will start the job with an empty state,
because this is a new job.
This is not a special for CUMULATE window, but for all Flink jobs.
If you want to restore a Flink job from a state/savepoint, you have to
specify the savepoint path, see [1].

Best,
Jark
