Caching of nodes in cache cluster

摘要

A replication count of a data element of a node of a cache cluster is defined. The data element has a key-value pair where the node is selected based on a hash of the key and a size of the cache cluster. The data element is replicated to at least one other node of the cache cluster based on the replication count.

1. A method, comprising:
defining, in view of at least one of an importance of a data element and an ability to re-create the data element, a replication count of the data element residing in a cache cluster; selecting, by a processing device, a first node of the cache cluster in view of the replication count and a hash of the data element, replicating the data element to the first node; responsive to determining that the first node has been removed from the cache cluster, selecting a second node of the cache cluster in view of the replication count and the hash of the data element; and replicating the data element to the second node.
