As big data deals with parallel processing of data it need a meta scheduler or an orchestrator to organize the activities. Orchestrator navigates various applications by governing error management and make easy interaction with other solutions. Orchestrator enables secure transferring of data through ...
BusTub 通过几个 Project,让我们对数据库的缓冲区管理、索引、执行引擎、事务控制等关键模块有相对深入的了解;Architecture of a Database System 则介绍了数据库系统的整体架构,让我们对数据库系统的每个关键模块都建立概念。BusTub 作为教育目的的数据库,其代码量不大,非常适合结合论文 Architecture of a Database Sy...
Parallel Architecture: Processes and Memory Coordination 几种coordination系统模型 Shared Memory The main challenge is to modify the query execution layers to take advantage of the ability to parallelize a single query across multiple CPUs Shared-Nothing The shared-nothing architecture is fairly common ...
Parallel process and memory coordination 多进程的存储模式分为三种:shared-memory,shared-nothing,shared-disk,分别对应三种不同程度的数据共享模式。 回到顶部 NUMA Non-Uniform Memory Access(NUMA)提供了一种cluster中带有独立内存的共享内存编程模型。Cluster内的每个system都可以快速本地内存,但是要访问其它内存速度会...
data stored externally to the database itself. Once the source data is loaded, the data present in the external tables can be processed using the capabilities of the data store. In big data scenarios, this means the data store must be capable of massively parallel processing (MPP), which ...
Volcano Parallel Database [12] 引入了在数据库中实现并行性的基本原则。该提议的框架引入了交换操作符,它通过流水线技术实现了两种并行性,即运算符间的并行性(通过流水线)和运算符内部的并行性(通过在不同进程上运行的运算符之间的元组分区)。该设计允许每个运算符在本地数据上独立执行,并与在其他进程中运行的运...
When you work with large datasets, it can take a long time to run the type of queries that clients need. These queries can't be performed in real time. And they often require algorithms such as MapReduce that operate in parallel across the entire dataset. The query results are stored sep...

We assume an application domain as our starting point for the domain core of a software architecture.Figure 9.3depicts this layered structure, as we saw earlier. These three layers are, from bottom to top, common abstractions of the business domain, the set of different parallel product domains...
