Primary purposes of my async replication are: 1. redundancy 2. prevent burst access to persistent storage (e.g. RDBMS) just after fail-over From client standpoint, it seems there is one memcached. But backend system consist two memcacheds - master and slave -. If master mcd is down, slave becomes new master with {key/value} data.

It allows memcached 1.6 to be used as a caching interface to MySQL Cluster, with a variety of possible cache behaviors. Or it can be configured so that NDB simply serves as a reliable persistent backend for memcache, making MySQL Cluster’s fault tolerance and geographic replication available to memcached. All of this can be specified on a per-key basis using memcache key prefixes, and several memcached servers can connect to multiple MySQL Clusters and serve different roles, all based on ...
