该项目地址为:https://github.com/twitter/snowflake是用Scala实现的。 雪花算法: (提高聚集索引的性能) 雪花ID是用一个64位的整形数字来做ID,对应.net中的long,数据库中的bigint,雪花算法的原始版本是scala版,用于生成分布式ID(纯数字,时间顺序),订单编号等。 自增ID:对于数据敏感场景不宜使用,且不适合于分布...
Snowflake是一种云数据平台,提供了高度可扩展的数据仓库解决方案。Snowflake .NET连接器是用于在.NET应用程序中连接和操作Snowflake数据库的工具。 证书错误通常指的是在使用Snowflake .NET连接器时,由于证书配置不正确或过期等问题导致连接失败。解决这个问题的方法如下: 检查证书配置:确保在连接Snowflake数据库时,使用...
用一种全新的雪花漂移算法,让ID更短、生成速度更快。核心在于缩短ID长度的同时,还能拥有极高瞬时并发处理量(50W/0.1s)。顶尖优化,超强效能(位数更短,速度更快),全新 SnowFlake 算法,支持 C#/Java/Go/Rust/C 等语言。

The SnowflakeNet models the generation of complete point clouds as the snowflake-like growth of points in 3D space, where the child points are progressively generated by splitting their parent points after each SPD. Our insight of revealing detailed geometry is to introduce skip-transformer in ...
.NET的snowflake 一般情况下,我们是使用自增长ID来做主键ID的。也有些哥们,是使用GUID来作为主键ID(本人并不建议采用GUID,主键一般是表的聚集索引,如果用了GUID做主键,每次insert会导致磁盘的移动,以及存储page的分裂,导致存储碎片)。 而用主键ID会导致“只有Insert完后,才能知道ID号”。
To address these issues, a novel method is proposed in this article for improving the generated point clouds with image-based methods using a deep learning network, called urban-SnowflakeNet, which comprises the following steps: 1) preparing and normalizing the roof's point cloud; 2) completing...
