By the way, I'm currently reviewing the Scheduler code. Do you
began to design the API queries or do you need help for that ?<br>

This will be an RPC api initially, because we know the
performance<br>
characteristics of the current RPC API, and doing
anything different<br>
to that is unnecessary risk. Once the new structure is:<br>
* stable<br>
* gated with unit and tempest tests<br>
* with a straightforward and well documented migration
path for deployers<br>
<br>
Then adding a RESTful API could take place.<o:p></o:p></p>
