In general, I believe it will.  But we'll also need to consider
efficiency for built-in on-memory "data source" (I thought we agreed
to avoid using "database" in this context to avoid confusion:-).  How
to meet these goals (whether we need to provide a special, separate
API where it needs to be efficient, which I'd like to avoid as much as
possible, or whether we can make it via some lazy evaluation, etc) is
an open issue.
