Feed: Featured Blog Posts - Data Science Central. Author: Kurt Cagle. Network graphs play a large part in both computing and data science, and they are essential for working with (and visualizing) both semantic graphs and property graphs. Nearly thirty years ago, AT&T produced a set of libraries called graphviz which were designed to generate various types of printed output. Over the years, the library has been adapted for different platforms and roles, and today is still one of the most widely used network graph visualization tools around. One of the most common libraries associated with graphviz is the DOT ... Read More

Feed: Recent Announcements. AWS IoT Analytics is a fully-managed service that makes it easy to run sophisticated analytics on massive volumes of IoT data without having to worry about the cost and complexity typically required to build an analytics platform. You can setup the service to collect only the data you need from your devices, apply mathematical transforms to process the data, and enrich the data with device-specific metadata such as device type and location before storing the processed data in a time-series data store for analysis. Then, you can analyze the processed data by running ad hoc or scheduled ... Read More

Feed: CIO. Author: . When enterprises adopt new technology, security is often on the back burner. It can seem more important to get new products or services to customers and internal users as quickly as possible and at the lowest cost. Good security can be slow and expensive.Artificial intelligence (AI) and machine learning (ML) offer all the same opportunities for vulnerabilities and misconfigurations as earlier technological advances, but they also have unique risks. As enterprises embark on major AI-powered digital transformations, those risks may become greater. "It's not a good area to rush in," says Edward Raff, chief scientist at ... Read More

Feed: AWS Compute Blog. Author: Benjamin Smith. Today, AWS is introducing Synchronous Express Workflows for AWS Step Functions. This is a new way to run Express Workflows to orchestrate AWS services at high-throughput. Developers have been using asynchronous Express Workflows since December 2019 for workloads that require higher event rates and shorter durations. Customers were looking for ways to receive an immediate response from their Express Workflows without having to write additional code or introduce additional services. What’s new? Synchronous Express Workflows allow developers to quickly receive the workflow response without needing to poll additional services or build a custom ... Read More

Feed: What's New. Author: Erin Gengo, Robert Bloom. As we reimagined data management across all of Tableau, we identified five pillars for the  migration process framework that dovetailed well with our Snowflake selection criteria, and would thereby increase trust and confidence in the data that everyone uses. These pillars are: staffing, governance, authentication, communication, and documentation.  We’ll first discuss staffing, governance, and authentication in this post, highlighting some key lessons learned, unexpected issues with responses, and recommendations to consider when migrating and tackling data sets—large or small, simple or complex. Staffing We don’t want to sugar-coat the complex undertaking of ... Read More

Feed: Planet MySQL; Author: Vitess; IntroductionIn this blog, I would like to explore Vitess Operator for Kubernetes. This post demonstrates the sample implementation of Vitess in Kubernetes topology. I also explore common DBA tasks by demonstrating how they are handled in the Vitess ecosystem. Vitess, out of the box, comes with a lot of tools and utilities that one has to either incorporate or develop to manage MySQL topology. Let’s take a look at the capabilities of Vitess in these areas and demonstrate how they are performed under the operator realm.PrerequisitesGKE AccountKubectlMySQL ClientInstall vtctlclient locallygo get vitess.io/vitess/go/cmd/vtctlclientDownload the Operator example ...

Feed: AWS Big Data Blog. Many organizations have an Apache Hive metastore that stores the schemas for their data lake. You can use Amazon Athena due to its serverless nature; Athena makes it easy for anyone with SQL skills to quickly analyze large-scale datasets. You may also want to reliably query the rich datasets in the lake, with their schemas hosted in an external Hive metastore. In response to customers’ requests, AWS announced Athena’s support for Hive metastore in early 2020. This extends the ability in Athena to query external data stores, with a combined benefit of better performance and ... Read More
