Ondřej Novák commented on COUCHDB-2859:
---------------------------------------
Please solve this, because caching is destroyed and prevent me to migrate to
the version 2.0. There are many options. You can for instance calculate fast
hash of the result (FNV-1A for instance) and use it as ETag. This feature can
be optional. It will still much faster than transferring result through the
network and parsing jsons on client.
