Things are about to get very different very quickly. Assuming by full BGP feed you mean both IPv4 and IPv6, you are soon going to need something that takes >500,000 routes. There are two reasons for this. First as the larger blocks of v4 space become unavailable due to runout, allocations of space will likely come as crumbs of smaller space. For example if someone requests a /16 they might get an equal amount of space in a bundle of smaller blocks that are not contiguous and can't be aggregated. This is going to lead to an explosion of routes in the v4 table.
This is already starting to happen. Starting in February, shortly after the last of the free IPv4 /8s were allocated, my historical graphs of the v4 and v6 routes we receive shows a slight, but noticeable uptick in growth rate.
