by sharding algorithms through =, >=, <=, >, <, BETWEEN and IN. They need to be implemented by developers themselves and can be highly flexible. Currently, 3 kinds of sharding algorithms are available extracts all kinds of scenarios by sharding strategies, instead of pro‐ viding built‐in sharding algorithms. Therefore, it can provide higher abstraction and the interface for developers to implement sharding in SQL. StandardShardingStrategy only supports single sharding keys and pro‐ vides two sharding algorithms of PreciseShardingAlgorithm and RangeShardingAlgorithm. PreciseShardingAlgorithm is compulsory

supports multiple sharding columns. Sharding Algorithm Data sharding can be achieved by sharding algorithms through =, >=, <=, >, <, BETWEEN and IN. It can be implemented by developers themselves, or using Java codes are not helpful in the unified management of common configurations. Writing sharding algorithms with inline expressions, users can store rules together, making them easier to be browsed and identify them. ShardingSphere currently supports the configurations of data nodes and sharding algorithms. Inline expressions use Groovy syntax, which can support all kinds of operations, including inline
