When reading DynamoDB DAX documentation - https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DAX.concepts.cluster.html
I noticed random alphanumeric character being used in the cluster endpoint. These are normally l6fzcv etc. Does anyone know what they stand for? Is it constant for DAX clusters in a region? Example endpoint from docs: dax://my-cluster.l6fzcv.dax-clusters.us-east-1.amazonaws.com
