Availability status seems not to be synced with Nextcloud Calendar like Microsoft Outlook with Teams.

Describe the solution you'd like

When a "busy" event is in progress in Nextcloud Agenda, set availability status in Talk as "busy" or "to not disturb" and eventually share informations about the event in progress as status message (in option).

Describe alternatives you've considered**

Microsoft does the same with Outlook and Teams/Skype for Business. If a calendar event is in progress with "busy" status, Teams status is "busy" or "in a meeting". If an event is "out of office", Teams status is "out of office".

Nextcloud is an open source and very powerful alternative to GAFAM, so it would be very interesting, in my opinion.

Some additions after talking with @miaulalala:

• If there is an event in your calendar and you are busy, the status text is set to "Busy"
• We could set the status type to "Do not disturb", but after thinking about it we don’t do it either for calls and this might make you miss messages you get while this meeting occurs. So we shouldn’t implicitly set it.
• If you happen to be in a call, where we use "In a call", this will override the calendar "Busy" state since it is more specific

@nimishavijay @jancborchardt I will use the existing "In a meeting" as a text.

But the question is which status we should use (Away isn't really correct, neither is DnD, nor is Online true either.) Can we create a new status which is "Busy" and add it to the status modal?

Would need a new icon for the status:

[nimishavijay]

I think it's a good idea to introduce a "Busy" status :) (for reference Teams has like a whole bunch of statuses and Slack has only available and offline).

The icon depends on what it would be used for. Some options:

🕓 Generic time icon, "busy" seems to be associated with "waiting" or "in progress"
📆 Calendar icon to indicate we are busy with an event

I am not able to figure out if the exsiting icons are MDI icons or emojis or something else. Do you know more about this?

I'm also wondering if we need the "Away" status now, it could most of the time be replaced by the "Offline" or "Busy" status (at least according to my understanding, what do you think?) cc @nextcloud/designers as well :)

Reopening because we had to disable the feature for now via #41714.

[miaulalala]

Reimplement this with an index table that is written to onEventCreate and onEventUpdate for the calendar

[ChristophWurst]

The purpose of the index will be to have quick access to events that start or end in a given timeframe (e.g. next/last 5mins).

[ChristophWurst]

OTOH we already have that, kind of, with firstoccurrence and lastoccurrence in oc_calendarobjects. The only thing missing are recurring events.

So the question is: how much performance benefit do we get from another index vs just using the existing infrastructure and a range request? Do we have flame graphs of the previous meeting automation and how it slowed down the system when a call started?
