MySQL Fabric: The --update_only option because one size does not fit all
Employee +1 Vote Up -0Vote Down

MySQL Fabric is a distributed framework that has high availability and sharding as targets. It organizes the servers in groups which use the standard MySQL Replication to providing fault-tolerance. Shards are assigned to different groups thus allowing applications to distribute both reads and writes and exploit resilience to failures as well.

Information on groups, servers and shards are stored in a MySQL Instance called state store or backing store. This instance is a repository for all this information and the engine used might be any supported by MySQL, although a transactional engine must be picked to truly provide fault-tolerance. …
