Feed: Planet MySQL; Author: Tiago L. Alves; Gaming, banking, telcos, and online services all are powered by fully-redundant and fault-tolerant software systems. At the heart of those systems, you can find MySQL Cluster — a distributed in-memory database having a minimum of five-9s availability (around 5 minutes a year). This open-source database provides nearly-linear scalability and real-time querying predictability at the microsecond level.To achieve such higher availability it’s crucial to ensure that each release is thoroughly validated. Thousands of automated tests are run daily, for different versions and platforms to ensure defects are detected early and fixed. Testing is everyone’s ... Read More

Feed: Planet MySQL; Author: MySQL Performance Blog; Recently, at Percona Live Europe 2019, Dimitri Kravchuk from Oracle mentioned that he observed some unclear drop in performance for MySQL on an ext4 filesystem with the latest Linux kernels. I decided to check this case out on my side and found out that indeed, starting from linux kernel 4.9, there are some cases with notable (up to 2x) performance drops for ext4 filesystem in direct i/o mode.So what’s wrong with ext4? It started in 2016 from the patch that was pushed to kernel 4.9: reported and discussed in LKML. As a result ... Read More

Feed: Planet MySQL; Author: Mark Callaghan; How do you use an LSM for analytics? I haven't thought much about it because my focus has been small data -- web-scale OLTP since 2006. It is a great question given that other RocksDB users (Yugabyte, TiDB, Rockset, CockroachDB) support analytics.This post isn't a list of everything that is needed for an analytics engine. That has been described elsewhere. It is a description of problems that must be solved when trying to use well-known techniques with an LSM. I explain the LSM challenges for a vectorized query engine, columnar storage, analytics indexes and ... Read More

Feed: All Oracle Press Releases. I just got back from a press tour in New York, where the most common question I heard was: What's Oracle's competitive advantage in the cloud? I believe it's the completeness of our offering. Here's why. The three main components of the cloud are the application, platform, and infrastructure layers. But most enterprises don't think about the cloud in terms of these silos. They take a single, holistic view of their problems and how to solve them. Because we play in all layers of the cloud—and are continually adding integrations between the layers—we are in ... Read More

Feed: Feed | Tractica. Author: Mark Beccue. Between 2008 and 2015, augmented reality (AR) was a technology gimmick looking for a market. Leveraging devices like smartphones, tablets, and, starting in 2012, smart glasses, innovators struggled with technical limitations, hype, and weak use cases. In mid-2015, the market began a time of recalibration. While the announcements about Apple’s ARKit and Google’s Android ARCore are splashy headlines, Tractica does not believe they will have significant impact in enterprise AR market adoption (explaining why is a blog post topic for another time) for some time. The most significant developments since 2015 in that ... Read More

Feed: Feed | Tractica. Author: Jessica Groopman. Since the advent of cars, the automotive industry has always embraced technological advances, but the pace of change has accelerated so rapidly that auto original equipment manufacturers (OEMs) worldwide are struggling to keep up. It is not just connected cars, or even autonomous cars that manufacturers are racing to [safely] bring to market; it is not just 5G connectivity shifting narratives around smart city interactions or in-car experiences; it is not just car-sharing and new business models with which they are experimenting; and it is not just artificial intelligence (AI) or computer vision ...
