I am also very much interested in compressing the underlying transfers using
PB. Where can we get the hack? :)
I am looking for something that is done after serialization so all features of
jelly remains. I.e., just before transfer, compress the data. Preferably with
some control, i.e., with each message i send i want to be able to say
if to compress and to what level of compression.
Currently i have to circumvent jelly by pickle and compress but i can only
do that when server sends to client since the client trusts the server.
However the server does not trust the client and thus, cannot allow pickled
objects to be unserialized.
maybe something like callRemoteCompressed...
