Snowflake的这种存算分离,计算节点本地盘做临时数据和缓存的架构被称之为multi-cluster,shared-data architecture。 (三)Snowflake架构 整个系统的架构总共三层,从下到上依次是Data Storage,Virtual Warehouse和Cloud Service Layer。Data Storage用S3来做远端存储,Virtual Warehouse相当于计算层,负责弹性处理query execution...
(提出snowflake,什么snowflake)We decided a fundamental redesign was in order. Our mission was to build an enterprise-ready data warehousing solution for the cloud. The result is the Snowake Elastic Data Warehouse, or \Snowake" for short. Snowake is a multi-tenant, transactional, secure, highl...
这部分共享数据一般在本地盘使用SSD存储,Snowflake把这种架构称之为multi-cluster,shared-data架构。 1. Architecture Snowflake是典型计算存储分离架构(multi-cluster, shared-data)。Snowflake主要包括三个模块,Data Storage(存储层),Virtual Warehouse(“muscle”, virtual machine构成的执行层), Cloud Services(“brai...
The Snowflake Elastic Data WareHouse 论文解读 简介:Snowflake是目前话题度超高的云原生数仓产品,从20年下半年上市到现在已经市值千亿了。它的流行进一步印证了云的重要性。纵观现在大大小小的数据库厂商,上云是必然要走的战略步骤,而snowflake则更加直接,类似于AWS Aurora或我们的PolarDB,它就是围绕着云基础设施构建...
Snowflake enables organizations to collaborate, build AI-powered data apps, and unlock data insights—all within a secure and scalable AI Data Cloud.
The result is the Snowflake Elastic Data Warehouse, or "Snowflake" for short. Snowflake is a multi-tenant, transactional, secure, highly scalable and elastic system with full SQL support and built-in extensions for semi-structured and schema-less data. The system is offered as a pay-as-...
一般的shared-nothing的数据库,由于计算和存储绑定,所以当有计算节点变更后,首先需要进行数据重分布,而snowflake的设计是不马上对缓存在本地磁盘的数据文件进行重分布,而是等后续的sql查询时,再逐步更新,这样就降低了有Worker node节点变更时,由于需要数据重分布而影响整个集群的性能。
