And skipping right to the end, my answer to “can it scale down” is just: “yes!”. Here’s my Raspberry Pi 4b, at home, consuming a few watts and pulling around 20GB of simplified firehose events per day. It’s an AppView indexing all cross-repo references (backlinks) in the AT-mosphere, often up to 1,500 created per second. It’s closing in on one billion backlinks, eating up an old SATA SSD connected over a salvaged USB adapter.
