Interval-Based Time Range Sharding Algorithm

Module

Since 4.0 the sharding algorithms are in their own artifact, me.ahoo.cosid:cosid-sharding (package me.ahoo.cosid.sharding, unchanged).

• Algorithm complexity: O(1)
• Usability: Supports multiple data types (Long/LocalDateTime/DATE/ String / SnowflakeId), while the official implementation converts to string first then to LocalDateTime, success rate affected by time formatting characters.
• Performance: Compared to org.apache.shardingsphere.sharding.algorithm.sharding.datetime.IntervalShardingAlgorithm, performance is 1200~4000 times higher.
