no, the database

when you build any kind of data storage system you have to deal with limitations, let's say you rent a VPS with a 25Gb disk, and that gives you about 18gb of free space to store your relay's events

reduces the cognitive burden of managing a relay, and also lets you optimize the cost of running one
