This was done by enhancing Apache AsterixDB, an open-source Big Data Management System that provides distributed data management for large-scale, semi-structured data. In this section, we present the user model

This implies both shared disks and shared everything. If you think this is too far out, consider this: - Even today there are large distributed systems with SMP nodes who in total run a distributed database system. - In the near future, we will find SMP structures on processor chips, ...
In machine learning, continuously retraining a model guarantees accurate predictions based on the latest data as training input. But to retrieve the latest
Cloud Systems is a new course that has been taught once (Fall 2014) in a seminar style, with class meetings focusing on the discussion of primary research literature. It combines advanced topics at the intersection of Operating Systems, Networks, Distributed Systems, and Databases. The primary go...
The result would be that those data sets are housed in different databases optimized for that kind of data and in different machines, so linear analysis simply won’t be an efficient option.

The endpoint abstraction is oblivious to the RDMA transport service and hence supports both reliable transport that offloads communication management to hardware and guarantees message delivery, as well as unreliable communication that requires error handling and flow control in software. Our design ...
We generated TPC-H databases with scale factors 200, 400, 800, and 1,600 and loaded them to 2, 4, 8, and 16 nodes, respectively, of the EDR cluster. We evaluate with TPC-H Q3, Q4, and Q10. While Q4 only joins two tables, Q3 and Q10 join three and four tables on different ...
Quick-and-dirty分析很多当前的并行DBMS让人失望的一点是,它们很难正确地安装和配置,因为为了让系统高效地工作,用户经常需要面对无数的调优参数。与安装两个商业化并行数据库系统的用户体验相比,开源MR实现提供了更好的开箱即用(out-of-the-box)用户体验;也就是说与这两个DBMS相比,我们可以更快速地让MR系统启动起...
