That would work, thanks. I tried to avoid replicating millions of
deleted documents together with a few hundred documents passing the
filter.

A solution might be this validate_doc_update function on the target
database:

function(newDoc, oldDoc, userCtx) {
    if (newDoc._deleted === true && !oldDoc) {
        throw({forbidden: 'do not create deleted docs'});
    }
}

This way all deleted documents will be transmitted, but at least not
written if there is no previous revision.


The problem for changed values remains: when the source database changes
type='foo' to type='bar', the target database keeps the old revision
with type='foo'.
