complex that there is not too much encapsulation, the combination of sharding keys and sharding operators are in the algorithm interface and achieved by developers with the most flexibility. • Hint Sharding operator is equal mark, the route result will fall into a single database (table); when sharding operators are BETWEEN or IN, the route result will not necessarily fall into the only database (table). So the operators. DistSQL enables users to operate Apache ShardingSphere like a database, transforming it from a frame‐ work and middleware for developers to an infrastructure product for operators. DistSQL

jobs scale out, so that they can focus more on business coding; At the same time, it can release operators too, so that they do not have to worry about jobs high availability and management, and can automatic
