Subject Interesting window behavior with savepoints
Date Thu, 12 May 2016 20:44:47 GMT

I was recently experimenting with savepoints and various situations in
which they succeed or fail. I expected this example to fail:


Basically, the first program runs with a count window. The second program
is identical except that it uses a time window instead of a count window.

>From what I've observed, most of the time when Flink can't successfully
restore a checkpoint it throws an exception saying as much. I was expecting
to see that behavior here. Could someone explain why this "works" (as in,
flink accepts the program with the savepoint from the first version of the
program), and if this is a bug?
