Solution 1: Linked Lists At each hash array slot, we store a linked list Each element of the linked list contains a key-value pair

Redis Cluster: an interesting problem about moving hash slots around Hash Slot Allocation Algorithm The hash slot algorithm is designed for distributed data storage and querying In the hash slot algorithm , there are a lot of

Solution 1: Linked Lists At each hash array slot, we store a linked list Each element of the linked list contains a key-value pair

peg slot Returns the number of keys in the specified Redis Cluster hash slot String · clusterDelSlots Removes slots from the cluster node

The command returns an array of keys names stored in the contacted node and hashing to the specified hash slot The maximum number of keys to return is

hashtag slot Each position of the hash table, often called a slot, can hold an item and is named by an integer value starting at 0 For example, we will have a slot named 0,

So, possibly the key slot distribution for our above configuration is as below: Master Node A contains hash slots from 0 to 5500; Master Node B
