Such a feature should be very usable :+1:
This should be implemented in a CachingClient
using 'doctrine/cache' as a caching backend IMHO.
Indeed sounds useful, questioning if it makes sense to use another backend to Cache, but it would work with ArrayCache or not? To avoid doing the same CouchDB requests in the same PHP request.
Currently each requests send to couchdb lacks of a
etag
validation header. This forces couchdb to regenerate a new response instead of sending only a header back. If we have the possibility to of sending such Requests, we could gain performance and throughput on the php application, couchdb and network usage).If we could send validation header in the HTTP request, couchdb would send a
HTTP 304 Not Modified
response back. Such responses would also be very helpful when using a gateway cache (e.g. varnish) infront of couchdb.Something we would need here, is the possibility to
If-None-Match
header in our request. Maybe as an optional parameter.etag
of the response and make it accessible when using the Query API. Currently that header is only accessible when using the HTTP client directly (like theStreamClient
orSocketClient
),Then a wrapper, like the
LoggingClient
, could be used to either put it into a local cache like APC or Memcached or just proxy the header to the client.What do you think @beberlei?
