Better performance for less: AWS continues to beat Azure on SQL Server price/performance

Feed: AWS Compute Blog. Author: Fred Wurden. By Fred Wurden, General Manager, AWS Enterprise Engineering (Windows, VMware, RedHat, SAP, Benchmarking) AWS R5b.8xlarge delivers better performance at lower cost than Azure E64_32s_v4 for a SQL Server workload In this blog, we will review a recent benchmark that Principled Technologies published on 2/25. The benchmark found that an Amazon Elastic Compute Cloud (Amazon EC2) R5b.8xlarge instance delivered better performance for a SQL Server workload at a lower cost when directly tested against an Azure E64_32s_v4 VM. Behind the study: Understanding how SQL Server performed better, for a lower cost with an AWS ... Read More

Radar trends to watch: March 2021

Feed: Radar. Author: Mike Loukides. For a short month, a lot happened in February–perhaps because the US elections are behind us, perhaps because COVID case numbers are dropping, perhaps for any number of reasons. Some of the most interesting articles I’ve seen have been about the Internet of Things, ranging from wireless peas to Elon Musk’s neural interfaces. AI and ML An AI system is being used to train crisis counsellors. Roleplaying plays a critical part in training staff at suicide prevention services. The AI plays the patient, freeing staff so that they can spend more time helping clients, rather ... Read More
Hubert ‘depesz’ Lubaczewski: Starting with Pg – where/how can I set configuration parameters?
Feed: Planet PostgreSQL. Previously I wrote about locating config files. The thing is – postgresql.conf is not the only place you can set your configuration in. In here, I'll describe all the places that can be used, why do we even have more than one place, and finally – how to find out where given value comes from. Obviously you can have config in postgresql.conf file. This file can include more files and directories. Look into your postgresql.conf and see if you have include_* params defined. For me, it looks like: #------------------------------------------------------------------------------ # CONFIG FILE INCLUDES #------------------------------------------------------------------------------ # These ...

This part, provide a conceptual-level reference architecture of a modern D&A platform. Parts 3 and 4, will explain how these two reference architectures can be used to modernize an existing traditional D&A platform. This will be ... Read More
The Ethereum Virtual Machine (EVM)
Feed: Featured Blog Posts - Data Science Central. Author: Monika Sangwan. Vitalik Buterin (https://vitalik.ca) conceptualized Ethereum (https://ethereum.org) in November, 2013. The core idea proposed was the development of a Turing-complete language that allows the development of arbitrary programs (smart contracts) for blockchain and Decentralized Applications (DApps). This concept is in contrast to Bitcoin, where the scripting language is limited and only allows necessary operations. The EVM is a simple stack-based execution machine that runs bytecode instructions to transform the system state from one state to another. The EVM is a Turing-complete machine but is limited by the amount of gas ... Read More
Evolving Schemaless into a Distributed SQL Database

Feed: Planet MySQL; Author: Ovais Tariq; In 2016 we published blog posts (I, II) about Schemaless – Uber Engineering’s Scalable Datastore. We went over the design of Schemaless as well as explained the reasoning behind developing it. In this post today we are going to talk about the evolution of Schemaless into a general-purpose transactional database called Docstore. Docstore is a general-purpose multi-model database that provides a strict serializability consistency model on a partition level and can scale horizontally to serve high volume workloads. Features such as Transaction, Materialized View, Associations, and Change Data Capture combined with modeling flexibility and ... Read More
Lætitia AVROT: Simply auditing your database changes
Feed: Planet PostgreSQL. This is something a lot of people want: being able to track changes happening on their database when and who ordered them. Well, I have good news, my friends, there is a native feature in Postgres that can help you achieve that exact goal!DDL and DML First things first, what are DDL and DML? Both DDL and DML are a subset of the SQL language. DDL means Data Definition Language (or Data Description Language). It means the SQL orders you need to create or modify database objects. An example of a DDL query is a create query ... Read More
Make way for the High Performance Parallel Dump & Load Utilities + How to use them

Feed: Planet MySQL; Author: Andrew Grimo; MySQL-Shell has had a set of “Util” object functions for almost a year as of this post. It is this added functionality that negates any reason someone would still need to use the old mysqldump client. It (mysqldump) helped the MySQL Community for a long, long time. It also introduced a large amount of garbage and messiness in with those bloated data files, as it really belongs to an older era. We can now move on ahead without it. This process of “moving ahead” is what I will demonstrate in this blog post. Note: ... Read More
