What if we split document metadata from document itself? E.g. pass
_id, _rev and other system or meta fields with separate object. Their
size much lesser than whole document, so it will be possible to fast
decode this metadata and decide is doc need to be processed or not
without need to decode/encode megabytes of document's json. Sure, this
adds additional communication roundtrip, but in case if it will be
faster than json decode/encode - why not?
