Hi Sveto,

Could you please explain what kind of specific data you want to put in
buildbot? Do you need the real time capabilities?

Data API is a middleware between REST and mq/DB apis, so in order to add
more Data API, you need to add db table, and db api to manage that. It is
not that simple.

There are much more simple way to create REST API. e.g:


If you really want to add REST endpoints to buildbot, you can create a web
plugin. This is something that is demonstrated in buildbot_travis:
You can see there the /config endpoint, which implement loading and saving
the buildbot travis config via the web UI.
