Modulo Sharding Algorithm
- Algorithm complexity: O(1)
- Performance: Compared to
org.apache.shardingsphere.sharding.algorithm.sharding.mod.ModShardingAlgorithm, performance is 1200~4000 times higher. And stability is higher, no serious performance degradation occurs.

Range Sharding Semantics
- Range (
Range) queries resolve nodes by span: a span covering at least the divisor returns all nodes. In particular, "unbounded" queries expressed asRange.closed(0, Long.MAX_VALUE)route to all nodes correctly (since v3.2.1, large spans are no longer affected by int overflow). - Sharding values must be non-negative integers (snowflake and segment IDs are non-negative); negative sharding values are not supported.
