Gary Tully commented on ARTEMIS-2768:
-------------------------------------
with ARTEMIS-2859, the size is now always associated with the target address,
which resolved the issue with negative size counts.
It makes me wonder if there is benefit in coalescing addresses into a single
page store in the wildcard case.
The page store does not track references, it always takes a copy of messages,
so there is no space saving to be had and I think there will be churn b/c the
consumption of messages won't be linear.
The use-case for page-store-name may be no more unless there is some other
benefit from sharing a page store.
