Hi Marco
You need to figure out why the checkpoint timed out(you can see the
consumed time of each period for one checkpoint in UI), if it indeed needs
such long time to complete the checkpoint, then you need to configure a
longer timeout.
If there are some checkpoint errors, we need first to figure out what
the problem is, in general, a checkpoint can split into some parts such as
barrie alignment(maybe there is some backpressure or something else, that
some barrier can't be received in time), sync duration(the thread is too
busy ...), and async duration(too much io/network process ...), etc.
Best,
Congxian
