As for the atomic increment, I take the answer is 'no, there is no atomic
increment, I have to pull the value to the client and send an update with the
new value'.
Saying atomic increment is probably confusing.
You cannot have Counters, the thing most people would think about when you say

Hi,
I think it does not fit the model of how C* does writes, but just to verify:
Is there an update-in-place possibility on maps? That is, could I do an atomic
increment on a value in a map?

yup, I understand the hint :-) However, since I am about to base application
architecture on these capabilities,

Sorry, but this fits into nothing I know about C* so far - can you explain?
