WebbA shard is a collection of one or more nodes in an ElastiCache cluster. It is created to support replication of data into various nodes in the ElastiCache cluster so that cache remains reachable in case of loss of few nodes. Depending on how the cluster mode is configured, a Redis cluster can have one or more shards. WebbQuestion #: 41. Topic #: 1.
