Is there any way to compress (gzip) the rules package to optimize network traffic between server and agent?
8:28 a.m.
We have a drools application composed of almost 1000 rules. The rules
deployment package has almost 8MB and we need to distribute it over a 100
Kbps network for offline use on some client machines.
If we could zip this package, it would require only 237Kbytes (instead 8MB).
It seems, however, the class org.drools.agent.impl.KnowledgeAgentImpl
doesn't support gzip compression.
Is it right? Is there any workaround for this problem?
Thanks in advance.

Whilst I don't believe there is anything "out of the box" could you just
not
write a JEE5 javax.servlet.Filter to perform the compression for you?

Ok, but I have to modify the class org.drools.agent.impl.KnowledgeAgentImpl
for it to do unzip the package on the client. There is no standard mechanism
for this?

Nothing out-of-the-box AFAIK, but a patch (or better yet a pull request)
is welcome.
Just wrapping both ends in ZipOutputstream and ZipInputstream should do
the trick,
but then we'd have always zipping, but we might want it optional.
If we want optional zipping, the client should include a header/argument
to the server
to ask it in zip format (similar like the HTTP protocol) and the server
should always support both (just do what the client asks him to do).
That we we don't rely in the client and server having to be configured
the same and crashing wierdly if they aren't.

Geoffrey Thanks for the reply,
I will include this feature as an option, because this problem is a
architectural risk of my project. How can I send the patch to the community
with these changes?
