研究方向
This is a design question, so start by reading the Deployment modes section of GETTING_STARTED to see how the three modes are wired. The open items are which broker topics must be shared between users in mode 2, whether any server-side code publishes to the broker, and how eccejobstore/eccejobmonitor behave when the client is closed. Done means a written decision on those points and a proposed selection option, not code.

描述
Summary
Allow a client to use a per-user local broker together with a remote data server, with jobs running on registered remote machines.
Current state
There are three deployment modes (GETTING_STARTED, "Deployment modes"):
- local: per-user broker on a Unix socket, local data (FileEDSI);
- central server (
-remote): the server's broker (TCP 8088) and its data server; - shared system broker.
There is no way to combine a local broker with a remote data server.
Motivation
A small group can run a data server on a rented cloud VM or a campus virtual server. Keeping the broker on the client means:
- one fewer port open on the server;
- broker passwords never leave the client;
- the server needs only the HTTP(S) data server.
Compute on the same or another host is a registered machine, as today.
To establish
- Which messages in mode 2 require a broker shared between users? Machine-registration change notices are one. Do any others exist, or are all topics per user (
ecce/<user>/)? - Does anything server-side (data server, scripts) publish to the broker? If so, it has no path to a client-local broker.
- Job monitoring: eccejobstore/eccejobmonitor run on the client and reach the compute host over ssh. With the client closed, monitoring pauses and resumes on the next start. Document this. Whether a server-side monitor is wanted is a separate question.
- How it is selected: an option of "Connect to a server", or a site/user setting. The first-start question should not gain a third choice unless needed.
Constraint
Mode 2 (central server with its broker) stays supported unchanged.
