Feed: Planet MySQL; Author: MySQL Performance Blog; One of the most exciting storage-related features in Kubernetes is Volume snapshot and clone. It allows you to take a snapshot of data volume and later to clone into a new volume, which opens a variety of possibilities like instant backups or testing upgrades. This feature also brings Kubernetes deployments close to cloud providers, which allow you to get volume snapshots with one click.Word of caution: for the database, it still might be required to apply fsfreeze and FLUSH TABLES WITH READ LOCK or LOCK BINLOG FOR BACKUP.It is much easier in MySQL ...

Feed: AWS Architecture Blog. One of the keys to identifying timely and impactful actions is having enough raw material to work with. However, this up-to-date information typically lives in the databases that sit behind several different applications. One of the first steps to finding data-driven insights is gathering that information into a single store that an analyst can use without interfering with those applications.For years, reporting environments have relied on a data warehouse stored in a single, separate relational database management system (RDBMS). But now, due to the growing use of Software as a service (SaaS) applications and NoSQL database ... Read More

Feed: AWS for SAP. Author: Kenny Rajan.

Feed: SAS Blogs. Author: Jim Harris. In this fourth post of my coronavirus terms series, I’ll examine some terms that are being discussed more often as we enter a critical new phase of the pandemic response. The second wave Coronavirus is called a once-in-a-century pandemic because the last one was just over a century ago. The 1918 flu pandemic, which lasted from February 1918 through April 1920, infected 500 million people (at that time approximately one third of the world’s population). Its estimated death toll was between 17 million and 50 million people. Of its four successive waves, its second ... Read More

Feed: Planet PostgreSQL. In the first part of this blog series, I’ve presented a couple of benchmark results showing how PostgreSQL OLTP performance changed since 8.3, released in 2008. In this part I plan to do the same thing but for analytical / BI queries, processing large amounts of data. There’s a number of industry benchmarks for testing this workload, but probably the most commonly used one is TPC-H, so that’s what I’ll use for this blog post. There’s also TPC-DS, another TPC benchmark for testing decision support systems, which may be seen as an evolution or replacement of TPC-H ... Read More

Feed: Teradata Blog. BC vs. DR vs. HA  The terms Business Continuity (BC) and Disaster Recovery (DR) are very often used interchangeably. While they are somewhat related, they are not the same thing. Business Continuity refers to the ability to maintain business functionality in the case of an outage, planned or unplanned, while Disaster Recovery is more IT-centric and technical in nature and refers to the ability to recover a particular component that might support one or more business capabilities.    As an example, we might have a loading platform that provides operational data feeds at 15-minute intervals into a relational database platform. This relational database platform is used by a critical business dashboard to monitor some Key Performance Indicators (KPIs) used by Business Leadership. In this example the data loading platform, ...
