Yes. It's better to profile and see.
I also discussed with Grainier and we think it's better to use "DEBUG" or
"TRACE" level when creating the gauge for memory consumption.
In that way, we can enable these kinds of gauges in runtime only when we
need. (The Carbon Metrics has a feature to support
I think it will be a good idea to run several rounds of testing to see if
this memory calculation is CPU intensive. And If this is CPU intensive then
this might have an adverse affect the overall performance of CEP/Siddhi as
well when executing in a limited resource setup.

Hi suho,
It does not have any impact on Siddhi's runtime performance. It just
affects on metrics reporting, which runs separately.
Thanks,
Grainier.

You have not answered my Qn
whats the impact on this when it comes to Siddhi's runtime performance ?

Hi Granier, Suho
The memory calculation will be a time consuming issue since it has to
traverse through the complete object tree. IMO, we should have the option
of executing matrix calculation in a separate thread and report back to the
caller with the result.
I think it's a valid case to have ma
I understand that Matrics reporting it getting slow.
At the meantime whats the impact on this when it comes to Siddhi
performance ?
If Siddhi query is also getting halted for 3 sec, then this is going to be
a bigger problem.

Currently, the memory usage calculation mechanism used on a Siddhi query
takes around 3 seconds. Therefore, when it comes to complex flow with
several of execution plans, it takes around (# of queries * 3) seconds.
Moreover, we have integrated carbon-metrics [1] (Gauges in this scenario)
with CEP f
