Hi all, I'm new to Storm. I'm finding the way to count latency per tuple.
What I exactly want are: (1) Mean latency of all tuples elapsed between a Spout generates them and last Bolt processes them (2) Maximum latency of all tuples elapsed between a Spout generates them and last Bolt processes them Example: If topology is Spout => Bolt0 => Bolt1 and tupleA is generated on 12:00:00 at Spout and finished on 12:00:05 at Bolt1, the latency of tupleA is 5 seconds. Especially, I want to calculate latencies of WourdCountTopology in storm-starter. Any advice? Thanks, Nakatani
