Design, implement, and validate CosId database sharding with core ModCycle, IntervalTimeline, CachedSharding, and SnowflakeLocalDateTimeConvertor APIs or ShardingSphere COSID_MOD, COSID_INTERVAL, and COSID_INTERVAL_SNOWFLAKE algorithms. Use for modulo routing, date/time partitions, Snowflake timestamp routing, exact/IN/range behavior, effective nodes, suffix naming, or routing tests. Do not use for choosing an ID generator unless sharding is the primary concern.
