New TelliCast settings (was: Re: [MSG-1] Pytroll/SatPy for EUMETCast)

What file_database_size do Windows receivers use and what has EUMETSAT proposed there?
In the latest TD-15.pdf EUMETSAT states "file_databas_size=20000000" so that's wrong as well?
Ernst, thanks for highlighting that. All TelliCast systems here are 64-bit so that's unlikely to be a major problem.
I see 20 MB, as per TD15:
so it's only control data which is stored. Buffer size can be set per channel, and I'm using:
name=EUMETSAT Data Channel 1
for example. So that's 8 MB. Having one setting per instance sounds like a good idea, and I'd probably set it to ~5 seconds of data - say 70 Mbps, 5 seconds, 350 Mbits, say 50 MB?
Perhaps EUMETSAT are already looking forward to the requirements for EPS-SG and MTG?
As the topic is of more general interest I've renamed it.

as long as I can remember (after the client changed) I have used file_database_size 200MB. I cannot tell whether this is because the
documented default is 250MB or this is copy and paste problem from the time when we did not use file_database_type=control yet.
It seems I have been prepared for MTG ever since 2014 :-). I have to look through my notes (if any!). Thanks for clarifying this.
