I'd like to be able to have views that are only updated on-demand,
that is,
when specifically requested to update, rather than whenever they are
read.
The use case is for a db that sees both heavy writes and heavy
reads. It may
be undesirable for views to be updated on each read; that causes a
lot of small
writes, probably meaning a lot more seeks. Allowing views to be
updated
explicitly rather than implicitly means that the writes can be
batched on an
application's terms, often improving performance.
Is this reasonable? I'm basing this on past experience with data
storage, not
on any CouchDB specifics.
Query views with the ?update=false parameter unless you want them to
update.
