To use MySQL Fabric, you must have a set of MySQL server instances running MySQL 5.6.10 or higher. One server is required for the backing store and at least one server must be added to a group. To use the replication features of MySQL Fabric, a replication topology of a master and at least one slave is required. To use the sharding features of MySQL Fabric, you should have the number of servers corresponding to the depth of the shards (the number of segments).
The configuration system changed in Fabric 1.5.5. The current system is documented here, and the old system is documented under Section 8.2.5, “Old Configuration System”.
