Gary Tully commented on ARTEMIS-2888:
-------------------------------------
I have settled on 'page-store-name' to allow a page store to be shared by a
hierarchy of addresses. This is necessary to avoid inconsistency in resource
usage calculations. A subscription can only deal with a single page store at
the moment, and if there is more than one in play it will compete to page and
update counters etc.. leading to problems.
<address-settings>
<address-setting match="A.#">
<page-store-name>A.shared</page-store-name>
</address-setting>
If wildcard routing is in play, and addresses will page, then we need to
explicitly indicate that page store that that hierarchy will use. Ie: this new
address setting is mandatory in this situation.
