A credential that identifies an AWS account or user to AWS (such as the AWS secret access key). Amazon Simple Storage Service (Amazon S3), Amazon EMR (Amazon EMR): The unique identifier for an object in a bucket. Every object in a bucket has exactly one key. Because a bucket and key together uniquely identify each object, you can think of Amazon S3 as a basic data map between the bucket + key, and the object itself. You can uniquely address every object in Amazon S3 through the combination of the web service endpoint, bucket name, and key, as in this example: http://doc.s3.amazonaws.com/2006-03-01/AmazonS3.wsdl, where doc is the name of the bucket, and 2006-03-01/AmazonS3.wsdl is the key.

Build an Analytics Strategy for an AI Driven Future with the Hybrid Cloud
Feed: Featured Blog Posts - Data Science Central. Author: Ronald van Loon. As a long-time part of this industry, I have spent a good part of the last decade talking about the digital transformation. Call it the digital transformation or the data-led transformation, but this transformation has been the talk of the town for a long time now. Not only are organizations geared toward achieving a better analytics setup, but they are also on the lookout for a more efficient data policy in the process. With many cloud service providers around us offering AI as a service, companies can tap ... Read More
Designing Apparel with Neural Style Transfer
Feed: Featured Blog Posts - Data Science Central. Author: Olha Zhydik. One of the things that excite the most about the predictive analytics of today is how quickly and bluntly it surpasses the existing benchmarks. Moreover, it penetrates the industries and activities where human creativity has traditionally dominated, adding a futuristic touch to the music, fine arts, fashion or architecture. Following the popular trend, we decided to explore the current capabilities of neural networks and find out if they can be of some real value for the fashion industry. Short time, big results In 2015, Google’s research team developed the DeepDream ... Read More
How to build smarter data integration in a multicloud world
Feed: IBM Big Data & Analytics Hub - All Content; Author: bharath-chari; Let’s say you’re the Chief Technology Officer of a bank or retailer struggling to infuse AI that aims to improve customer experiences. You likely face three main challenges:Data sprawl: Your customer data is currently on multiple clouds, including on-premises and a cloud data lake storage repository. But the data often exists in different formats in Db2, Oracle and other databases—and those databases are being used by transactional systems in different departments. Data latency across clouds and systems can be a serious concern in a multicloud environment, specifically when ... Read More

Gosset part 2: small sample statistics
Feed: R-bloggers. Author: Roel M. Hogervorst. From one representative barrel of malt extract they had taken a lot of samples. happen if they drew and averaged multiple samples. By simulating these draws from one barrel they generalized this pattern towhat would happen if they sampled from the all of the barrels.And that is what I will show in R code. Simulating drawing from a barrel First the goal in clearer language.We want to know how many samples you have to draw to know what the real degree saccharine level of the barrel is. With a 10 to 1 odds of ... Read More
MySQL Parallel Index Range Scans: One is Sometimes Better Than Two
Feed: Planet MySQL; Author: Øystein Grøvlen; As presented at the Percona Live Conference in Austin in May, at Alibaba we are working on adding support for parallel query execution to POLARDB for MySQL. As discussed in the presentation, we observe that parallel range scans on secondary indexes does not scale very well in MySQL. This is old news. Mark Callaghan reported this several years ago, and this does not seem to have changed. In this blog post, I will investigate what effects using a multi-processor machine have on the scalability of parallel index range scans. I will run a variant ... Read More

Feed: Cloud Data Transformation Software | Matillion. Author: Julie Polito; Data volumes are expanding at an unprecedented rate. Enterprises are moving to the cloud. You hear this information over and over, and you definitely hear it from us. It’s very easy to get caught up in how many zettabytes of data we’ll all be producing by 2025, and how data and cloud computing affect us all on a global scale. But what do data growth and other issues that mean for how you do business right now? How does what you read track with the experiences you and other organizations ... Read More
Rowid Filtering Optimization
Feed: MariaDB Knowledge Base Article Feed. Author: . Rowid filtering is an optimization in MariaDB 10.4. Its target use case is as follows: a table uses ref access on index IDX1 but it also has a fairly restrictive range predicate on another index IDX2. In this case, it is advantageous to: Do an index-only scan on index IDX2 and collect rowids of index records into a data structure that allows filtering (let's call it $FILTER). When doing ref access on IDX1, check $FILTER before reading the full record Example Consider a query SELECT ... FROM orders JOIN lineitem ON o_orderkey=l_orderkey ... Read More
Oracle OpenWorld: A Vision to Disrupt the Cloud
Feed: Oracle Blogs | Oracle Blogs. Oh, #OOW19, where should I start? There were compelling sessions, brilliant people, and an entire playpen of puppies. But the most exciting part hands down was the technology and new concepts announced at the event, starting with this simple yet bold claim that kicked off Oracle OpenWorld 2019: Oracle is a people-focused, data-driven organization. This message was everywhere at the conference. I saw proof of it in the technology I was fortunate enough to experience and heard about it firsthand from customers already using it at their organizations. It was also evident at the ... Read More
Orchestrate Amazon Redshift-Based ETL workflows with AWS Step Functions and AWS Glue
Feed: AWS Big Data Blog. Amazon Redshift is a fully managed, petabyte-scale data warehouse service in the cloud that offers fast query performance using the same SQL-based tools and business intelligence applications that you use today. Many customers also like to use Amazon Redshift as an extract, transform, and load (ETL) engine to use existing SQL developer skillsets, to quickly migrate pre-existing SQL-based ETL scripts, and—because Amazon Redshift is fully ACID-compliant—as an efficient mechanism to merge change data from source data systems.In this post, I show how to use AWS Step Functions and AWS Glue Python Shell to orchestrate tasks ...
