Event groups/categories to support services delivering large amount of events

[wouterdeman-uhasselt]

Use Case

We just started with event catalog and are active in education having a student information service that delivers 50+ events/messages (academic structure, personal student information, student financing). Works great but the diagrams on domain level or at service level are now bloated with all the messages/events.

Proposed Solution

Lets say we have a Student information service that sends lots of messages/events but we can group/categorize the events/messages in a certain context (academic structure, student personal information, ...) which could be used visually to have "Student information service" (producer) => Academic structure messages + student personal information messages => CRM service (consumer). An end user could open up (zoom in on) the group/context of academic structure messages and you would then see "Student information service" (producer) => Program created event / Program updated event / ... => CRM service (consumer)

This would keep domain / service overview more usable while still offering a deep dive towards the events/messages in combination with focus mode if you would search for an event.

AS IS

Potential TO BE

Implementation Notes

Adding categories/group names/tags on events
Making the categories/group names/tags usable in charts of domains / services when a large amount of messages occurs (10+ ?)

I like the idea, gonna spike some POCs when I get a chance to see how this would place out.

Thinking something like

sends:
	id: my-message
	version: 1.0.0 (optional)
	group: my-group

Anything with groups would be grouped up and not shown until you click to expand them or drill down.

Clicking on a group would show this? or expand the nodes in the graph?

@boyney123 Expanding the group would show the messages, could be in focus mode or in the general view but then you would need a list of expanded groups on the right/left side (like the legend box) to collapse them back in. Expanding groups could be via clicks in the graph or you could also list the groups on the right/left side which would expand/collapse, maybe this is more user friendly.
