Now, those tables hold data for the drones for a simulation. Each simulation dataset will grow to around 10 GB in around 6 months. Since the data is not related in any way I was thinking in separating each simulation into it's own database. That way it would be much easier for me to, at later date, move some of the databases to other servers (when dataset grows beyond the original server storage capacity limit). But. At this time I have around 600 simulations, that would mean creating 600 databases, and in future there could very well be around 5000 simulations. Is postgres going to have 'issues' with that large number of databases? Or do I model my system in a way that each database holds around 100 simulations? Mario
