Hi Val,
We do create lots of object. I am getting 1M data points event minute. For data
affinity, I create a key object for each data point. As I mentioned earlier I
have two stages of processing. We create new key on both stages. So, creating
close to 2M new keys every minute. I have changed that and running the test
now.
Also If I understand correctly then when I do get() on cache, it creates a copy
of the object and return that copy. Do you think turning off that behavior will
help?
Thanks,
Biren

Biren,
I see the jump and I actually see GC pauses as well (the longest one is the
last line in log_2.txt). BTW, I don't think there is an quick jump, GC pause
most likely blocks the monitor thread as well, so it just looks like a jump.
Apparently, all these 30 seconds were spent in GC, and I'm pretty sure this
is causing the issue.
It looks like you're doing something that generates too many objects. My
suggestion would be to use JFR [1] to profile object allocations and check
what's going on.

It is allowed to use cache API from receiver. To remove entry using
streamer, you can use removeData() method.
