Understanding Message timeout

[Manikandan <ma...@gmail.com>]

Hi

With respect to the
TOPOLOGY_MESSAGE_TIMEOUT_SECS<http://nathanmarz.github.io/storm/doc/backtype/storm/Config.html#TOPOLOGY_MESSAGE_TIMEOUT_SECS>*,
*is this the time that the spout waits for the ack or the fail callback
before timing out?
Or is this the time that the acker does not get any ack or fail from the
bolts in the topology?

I am trying to understand if this timeout decision is taken entirely by the
spout itself or acker does it for spout (the topology may still be
contacting the acker through the ack call but its taking longer time to
process)?

Please clarify.

Thanks
Manikandan
