@chenyongyin Can you use `ShardingSphere`` 5.2.1` and try it?

Hi @chenyongyin , I checked `SnowflakeKeyGenerateAlgorithm.generateKey()`, `sequence` will increase `1` in every call.
What's the system TPS? Maybe it's too small. Since snowflake algorithm generated id will be changed in every millisecond.
