Execute latency much higher than process latency

[Nathan Leung <nc...@gmail.com>]

Hi,

Does anyone know what might cause the execute latency of a bolt to be much
higher than the process latency?  I've heard that code after the ack()
method is called can cause this, but ack() is literally the last part of my
execute() method.  Also, sometimes this happens only on some instances of a
bolt, and not on others.

Here's an example (UI was set to show results for last 10 minutes):
ExecutorsIdUptimeHostPortEmittedTransferredCapacity (last 10m)Execute
latency (ms)ExecutedProcess latency (ms)AckedFailed[249-249]3d 8h 1m 2s
<Host>67038920178402.196177.55874206.37374000
Thanks,
Nathan
