For management clients it is tedious and awkward to read resources / attributes in big
domains (e.g. return the state of all running servers across all hosts which are part of
server group "foo"). Today this requires to setup multiple composite operations
*on the client* which need to be executed in a specific order. This proposal suggests a
new operation which collects all relevant information *on the server* and returns only the
relevant data in one go to the client.
In the admin console we often need to read specific attributes across a domain or across a
deeply nested resource:
- List all enabled data sources of the current profile
- Show the port offset of all running servers across all hosts
- Get all users which belong to role Operator
Even for small domains with two server groups and a small number of servers this procedure
is awkward and error prone. What makes it even more difficult is the asynchronous nature
of the admin console. Soon you end up in a deeply nested callback-hell. Besides that these
'queries' lead to poor performance for big domains with tens of groups, hosts and
# Proposal / Prototype
The GitHub repository at  contains a more detailed description of the problem statement
and a working prototype. This includes details such as how to address the requested
resources, how the information is retrieved and how to handle errors.
The proposal also includes a way to filter and reduce the resources against a list of
attributes and values *before* the response is sent to the client.
