Shared-Nothing 架构 shared-noting 架构,每个节点都有自己的 CPU、内存和磁盘,并且一般通过网络层进行节点之间的通信,计算节点可以自由独立扩展,规避了 shared-disk 的集中式存储瓶颈。 图片 常见的 shared-nothing 架构的数据库有 DB2、Vertica、Greenplum。 Snowflake Architecture Snowflake 团队采取了独特的方法。他们...

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 ar...
那个年代(2012~2014) Shared-nothing architecture成为数据仓库主流(如Teradata、Vertica),原因1:可拓展,原因2:廉价硬件 (虽然是大流,可我们snowflake偏偏不随大流,不用sharing-nothing 商业上性价比最高的,是share-disk,全部用一块盘存,简单来说,是多台机器共享一个分布式存储的大硬盘 大流的share-nothing架构有什么...
As such, data management is as simple as in shared-disk architecture with performance and scale-out benefits of the shared-nothing architecture. Snowflake architecture diagram Snowflake has a multi-cluster, shared-data architecture that consists of three separate tiers, namely data storage layer, ...
In this Snowflake architecture blog, you will learn how Snowflake combines shared-nothing and shared-disk structures to form a hybrid Snowflake architecture. It also introduces you to the distinguishing features of Snowflake Data Warehouse. Blog...
(谈主流的Shared-nothing架构)Shared-nothing architectures have become thedominantsystem architecture in high-performance data warehousing, for two main reasons: scalability and commodity hardware. In a shared-nothing architecture, every query processor node has its own local disks. ...
Snowflake Architecture & Compute Shared Disk, Shared Nothing Architecture Cluster Nodes and Snowflake Clusters CPU & Memory Resources in Clusters Disk Storage and Network Communication Storage Layer and Cloud Service Layer Database Query Layer & Data Cycle ...
Processing Architecture – Snowflake uses a shared-nothing processing framework. Each compute node has its CPU, memory, and storage and processes the data independently. This allows easy scaling by adding more compute nodes to the cluster. ...
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。
