Isn't it still true that EOF still needs to run the query to determine
which objects match?
That is, it still sends a query for primary keys to the database but
does not fetch the data but rather uses the in-memory cache to resolve
faults.

Any
subsquent fetches or fired faults will only go as far as the snapshot
layer. There should be no further DB access. I've verified this
recently
with 5.2.3.
Are you perhaps using a fetch spec with "refreshes refetched objects"
set
to true? I'm not sure what would happen in that case.

So the docs for "cache in memory" on an entity make it sound like WO
won't need to hit the database again after the first full load. I'm
not seeing this behavior at all, though, which leads me to believe
I've misunderstood this flag. Even with cache in memory, I still see
queries to retrieve entities of the particular type that i flagged.
What is the actual definition of this field?
