Nile CEO here. You can place tenants on multitenant DB or a dedicated Postgres DB. Placing the tenants on multitenant DB is the default. This has no cold start time since the instance/container is shared. If you choose to place a tenant on a dedicated tenant DB, you would have cold time of a few seconds. We are building this as we speak and will have more numbers to share soon. However, if you have chosen to place a tenant on a dedicated DB, these typically would be critical customers who are actively using the DB and may never want the instance to go down. We are exploring provisioned compute tokens for this purpose.
