* info in this table was not "per client" (like slot_cache) so it was containing a list of all master nodes of all cluster-clients ever instantiated * list was always growing (there were just appends to the table) * list of master nodes can be already obtained from the slots info already cached per client (this eliminates the need of an extra "nodes" query to redis)
