Thank you! I know that but we are still unable to find the problem. If I
turn on the acker but do not anchor the tuple does that mean the tuple
will still not be processed in a reliable way?

No, you need something to process the acks otherwise there's no way to
tell what has processed successfully and what is timing out. It's
better to figure out why enabling acking is causing your topology to
fail. That sounds ... bad.

Thank you very much for the quick response. By the way I forgot to
tell that I disabled the acker in the topology since the topology
may die after a few seconds if I do not turn off ackers. In this
case is it still possible to do guaranteed message processing for
some of the bolts? Thank you!!

When you emit from bolt c do not anchor the output tuple to the
input tuple.

Hi everyone,
I am confused about reliability API of storm. It seems
that guaranteed message processing is only for spout. What if
I need to guarantee message being processed in a subset of
bolts? For example, bolt A, B, C are connected and tuples are
processed from A to B and to C, what should I do if I want
tuples passed through these three bolts being processed
fully? I mean once a tuple is passed to A then I should make
sure that this tuple is processed in B and C but after that I
do not care whether it is lost or not? Thank you very much!!
Best wishes!!
