[my numbers match yours] It's very interesting that we made more or less the same choices: NFS on a LAN for cold storage. In practice, I haven't seen performance penalties either. I will certainly standardize on that. If needed, 'reviving' the cold stored data is as simple as copying it to other machines-- which will also offer sharding. My only reproach is that servers have to be identical, as clickhouse doesn't seem to be able to take into account the speed differences. My backup servers are quite different from the production server, but in an emergency I'd like to use them all.
