Hi,
afr supports an option "read-subvolume". Reads are by default scheduled to
the node set in this option. Hence In your configuration, each client can
use a different value for the above option to spread out the reads to
different servers.

A centipede was happy quite, until a toad in fun,
Said, "Prey, which leg comes after which?",
This raised his doubts to such a pitch,
He fell flat into the ditch,
Not knowing how to run.
