Feed: Actian. Author: Pradeep Bhanot. Social relationships hold a wealth of information about your customers, employees, and suppliers that (if you have the tools to harness them) can provide you valuable insights about the factors that influence behaviors that ultimately impact your bottom line.  The challenge with analyzing and visualizing social relationships is that the underlying data doesn’t match well with the relational data structures that most data warehouses are designed around.  The use cases that your company needs to embrace to create competitive advantage are too complex for most relational databases to handle, and as a result, you may ...

Author: joeleslie. At NuoDB, we’ve not only been working hard to improve upon on our distributed SQL database engine, but also to make it easier to adopt NuoDB into CI/CD pipelines. NuoDB is a ANSI standard and ACID compliant SQL database that is suitable for all common deployment models, such as bare-metal, virtual machines, cloud and hybrid-cloud, and most recently container-based environments, such as Red Hat OpenShift Container Platform. At its core, NuoDB is designed to be highly scalable and fault-tolerant with the ability to load-balance across a distributed architecture.If you would like to try NuoDB’s Community Edition (CE) in Docker, ...

Feed: Planet MySQL; Author: MySQL High Availability; Data nodes are the distributed, sharded storage core of MySQL NDB Cluster. Its data is usually accessed by MySQL Servers (also called SQL nodes in NDB parlance). The MySQL servers each have their own transactional Data Dictionary (DD) where all the metadata describing tables, databases, tablespaces, logfile groups, foreign keys, and other objects are stored for use by MySQL server. The MySQL server DD, introduced in version 8.0, has enabled improvements such as atomic and crash-safe DDL and the INFORMATION_SCHEMA implementation among other things. At the storage engine level, NDB has its own ... Read More

Feed: Planet MySQL; Author: Yves Trudeau; As the second part of the earlier post Give Love to Your SSDs – Reduce innodb_io_capacity_max! we wanted to put together some concepts on how InnoDB flushing works in recent Percona Server for MySQL versions (8.0.x prior to 8.0.19, or 5.7.x). It is important to understand this aspect of InnoDB in order to tune it correctly. This post is a bit long and complex as it goes very deep into some InnoDB internals.InnoDB internally handles flush operations in the background to remove dirty pages from the buffer pool. A dirty page is a page ... Read More

Feed: Liquid Web. Author: Jerry Vasquez; Why Prevent and Thoroughly Remove Malware From Your Site? For small-to-mid-size businesses (SMBs) and enterprise organizations, finding, removing, and preventing malware is increasingly critical for risk management and digital trust. Security risks and concerns are rising globally for digital technology. The Experian 2018 Global Fraud and Identity Report, with input from over 5,500 consumers and 500 businesses worldwide, reveals what consumers think of security protocols and gauges how confident businesses can accurately identify their customers. Key findings from this report include: 91% of consumers own smartphones and mobile devices, while 83% own laptops. 90% ... Read More

Feed: MemSQL Blog. Author: Rick Negrin. There is a trend in industry which says that modern applications need to be built on top of one or more special-purpose databases. That every application benefits from using the best-of-breed technology for each requirement. And that the plethora of special-purpose options available from certain cloud providers is reasonable to manage. That’s all BUNK. The reality is that navigating the choices, figuring out how to use them effectively, and dealing with the ETL and inevitable data sprawl, is so difficult that the pain far outweighs any technical advantage you might get. In the vast ... Read More

Feed: Recent Announcements. Canaries are configurable scripts that follow the same routes and perform the same actions as a customer. This enables the outside-in view of your customers’ experiences, and your service’s availability from their point of view. You can run a canary once, or on a regular schedule. Scheduled canaries can run 24 hours a day, as often as once per minute. The canaries check the availability and latency of your endpoints, and can store load time data and screenshots of the UI. The canaries can also be customized to check for availability, latency, transactions, broken or dead links, ... Read More

Feed: Cambridge Intelligence. Author: Andrew Disney. Colors can make or break your data visualization.A carefully selected color palette helps you to harness the pre-attentive processing powers of the human brain, and makes insight clearer and easier to find. A badly chosen color palette obscures the information your users need to understand, and makes your data visualization less effective and harder to use.This blog post explores some data visualization examples, basic color theory, and explains how it can help you design visualizations that look good, and make data more compelling.Let’s start with some examples to show you the importance of choosing ...

Feed: Planet MySQL; Author: Bernd Ocklin; The MySQL NDB Cluster team works on fundamental redesigns of core parts of NDB architecture. One of these changes is the partial checkpoint algorithm. You can now take full advantage of it when building much larger clusters: NDB 8.0 can use 16 TB data memory per data node for in-memory tables. 3-replica 5 PB clusters can be build with disk data. The new partial checkpoint algorithm executes restarts up to 4x faster, reduces checkpoint times by a factor of 6x in typical set-ups and minimizes cluster’s disk space consumption. In addition the new checkpoints ... Read More
