Redis Notes Redis Cluster and Hash Slots

Redis Notes Redis Cluster and Hash Slots redis hash slot Redis Cluster uses a hash slot-based partitioning scheme to distribute data evenly across the nodes Each key is assigned to one of the 16,384 redis slot Effectively, the “key-set” of our HASH is our “set” data structure Our strategy results in a view of the HASH like this: redisHashKey: { valueToStore1: 1,
