[Buildbot-devel] Is possible to have more than one server in git_buildbot.py?

Wed Jan 8 08:12:34 UTC 2014

Hi,

Buildbot supports a 'multi-master-mode'. See: 
http://docs.buildbot.net/current/manual/cfg-global.html#multi-master-mode

The doc suggests to:
  - have one buildbot master configured with just the scheduler and 
change sources;
  - and then other masters configured with just the builders.

IMO, this should do what you need.
