Sorry, yeah it was a little radical. I started with intent to remove
references to the query name used as a cache key, and noticed that a
number of other things were incorrect. I was unsure how to just strip
the inaccuracies and still preserve the document flow. So I went with
a slash and burn (which would've been justified if I'd provided an
equivalent replacement).
So yeah, let's revert the page, and maybe I'll take another shot at a
more comprehensive rewrite of this chapter (sometime in the future...).

That's pretty slash and burn... I think that perhaps some useful
bits of information got lost in that edit. For example:
This cache is defined on per application basis in the [Cayenne
model | configuring caching behavior]. A single number configured
in the model defines the total number of records (of every type of
entity) which can be stored within the cache.
Is that no longer the case? If we bring this text back, I'll add a
small screenshot.
Query caches can be shared between all the queries within the
context (LOCAL_CACHE) or between contexts (SHARED_CACHE).
SHARED_CACHE does not work in ROP Cayenne.
Behind the scenes, for a LOCAL_CACHE Cayenne stores objects or
DataRows (depending on which kind the query fetched), and for a
SHARED_CACHE it stores DataRows which are converted to the target
context objects on every cache hit.
Is this now incorrect?
Refresh query is still being developed and further information can
be found [here | refreshquery].
We lost the link to the refresh query page without this text.
Unless you have an objection I'd like to try rewriting that page.
Please let me know if anything of the above text is incorrect.
