每个计算节点在本地磁盘缓存一些 table data,本地磁盘专门用来放置临时数据和缓存(建议用SSD),缓存变热后,性能将达到甚至超过share-nothing system,我们将这种架构称为multi-cluster,shared-data architecture(理解:①同一个虚拟仓库下,工作节点共享‘一块’cache,②由于采用S3,每个VM可以访问所有数据,这叫做共享...
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 a...
Data Architecture – Snowflake is a cloud-based data warehousing platform that uses a multi-cluster shared data architecture. Data is stored in separate compute and storage layers, allowing separate scaling of compute and storage resources. The data is stored in proprietary c...
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...
称作Multi Cluster，Share Data Architecture，这个新架构有不少好处：1）Share Disk是个老概念，原来的...

Multi-Cluster, Shared Data Architecture Snowflake架构分为三层,存储,计算和服务 Data Storage This layer uses Amazon S3 to store table data and query results. 注:2016年的论文发表时的存储支持情况,当前除了支持S3,还支持 Google Cloud Storage, Microsoft Azure blob storage。避免了云服务商的lock in。
