Extend nats server

[Ivo Kovacka]

Hi all, 

is it possible to extend nats server in the manner that we are able to modify the payload coming from event before it is sent to all subscribers?

Thanks a lot,

Ivo

Not at this time but this is planned as an extension to subject callouts architecture. Auth callouts is in our dev nightly builds and will be part of the 2.10 release. General subject callouts are planned for 2.11 and would allow this.

You could do your own version of this today if interested by sending on one subject that gets transformed and placed into a different stream before consumers process.
