Following up on the previous thread:

Here is the latest data, which includes the Ocata release:

As you can see, there has been one jump in memory usage. This was due to 
the TripleO patch https://review.openstack.org/#/c/425717/

Unlike previous increases in memory usage, I was able to warn of this 
one in the advance, and it was deemed an acceptable trade-off. The 
reasons for the increase are unknown - the addition of more stuff to the 
endpoint map seemed like a good bet, but one attempt to mitigate that[1] 
had no effect and I'm increasingly unconvinced that this could account 
for the magnitude of the increase.

In any event, memory usage remains around the 1GiB level, none of the 
other complexity increases during Ocata have had any discernible effect, 
and Heat has had no memory usage regressions.

Stay tuned for the next exciting edition, in which I try to figure out 
how to do more than 3 colors on the plot.

cheers,
Zane.
