Subject [jira] [Commented] (COUCHDB-1743) Make the view server & protocol faster
Date Fri, 03 May 2013 13:38:16 GMT

Benoit Chesneau commented on COUCHDB-1743:
------------------------------------------

I know about ios. I am actually using another implementation of the view server. Ironically
while asynchronous behind it is still synchronous for couchdb.

I disagree with "CouchDB already achieves this with JSON as the fundamental unit of transportation.
" It is actually really costly, especially since we are storing binaries. Also I' mot sure
that JSON is the best protocol ever for such things. Anyway I specifically want to remove
the steps:


Get binary
Encode to json string
send
receive
decode to json
do a thing
encode to json string
send
receive
decode
do a thing
store it


stdio means stdin/stdout so not so much over the network. I specifically intent the possible
usag e of unix/tcp sockets or any other transports if needed. The reason is that sometimes
depending on the need you may want to the calculation at another level or on another machine.


Data between a // or not view server doesn't change the thing that at the end the data need
to be written on the disk.  So again having a // implemtation of the view server or not doesn't
change anything to the couchdb internals. couchdb only have to p[ass the data to the vies
server and provide a way to write them. 

I read it, but it doesn't answer to the drawbacks I expose. I agree that each messages could
be tagged (taskid) but that doesn't imply a // implementation. It can be used for another
usage. 

Can you put your proposal on the wiki so we could play with it eventually?
