Feed: Planet MySQL; Author: MySQL Performance Blog; In this blog, I want to evaluate Group Replication Scaling capabilities in cases when we increase the number of nodes and increase user connections.For testing, I will deploy multi-node bare metal servers, where each node and client are dedicated to an individual server and connected between themselves by a 10Gb network.Also, I will use 3-nodes and 5-nodes Group Replication setup.Hardware specifications: System | Supermicro; SYS-F619P2-RTN; v0123456789 (Other) Service Tag | S292592X0110239C Platform | Linux Release | Ubuntu 18.04.4 LTS (bionic) Kernel | 5.3.0-42-generic Architecture | CPU = 64-bit, OS = 64-bit Threading | ...

Feed: Redis Labs. Author: Pieter Cailliau. The newly announced RedisGraph 2.0 module brings a number of improvements, including increased Cypher support, full-text search, and it enables graph visualization. Just as important, however, the latest version of RedisGraph delivers significant performance improvements: with latency improvements up to 6x and throughput improvements up to 5x. Let’s take a look at those performance gains and the benchmarks used to demonstrate them. When we released RedisGraph 1.0 back in November 2018, we shared benchmark results based on the k-hop neighborhood count query. The new RedisGraph 2.0 includes new features and functionalities that support more-comprehensive ... Read More

Feed: Actian. Author: Lewis Carr. In December, January, and February, I posted a short series of blogs on Flat file systems. The series of blogs focus on the continued use of flat files and why they are no longer viable for use in the future.The first installment focused on flat files and why embedded software application developers readily adopted them. Then in the second installment, I discussed why embedded developers are reluctant to use databases. The third installment looked at why developers cling to the flat file systems. The final installment provided a checklist for embedded developers migrating off flat files ... Read More

Feed: Liquid Web. Author: Andrew Hartnett; At Liquid Web we are continuously improving our customer’s experience by increasing reliability and performance. In that spirit of continuous improvement, we have been working on placing additional DNS servers spread around the world. These additional servers are strategically positioned so that they provide a local DNS server option for visitors to your site (wherever they are), and this significantly reduces first-visit load times. First-visit load times are critical as this significantly impacts SEO scores and is a top indicator if a customer will stay on a website or not. Before we get into ... Read More

Feed: Big Data Made Simple. Author: Philip Piletic. Perhaps the single biggest problem with data lakes is the fact that it seems like nobody can clearly define what they’re best used for. Computer scientists will say that a data lake is nothing more than a repository of data that’s stored in a natural raw format, but that definition sounds awfully close to a file system. There’s no reason that server managers will want to explore some exotic solution when a Btrfs volume or an Apache Flafka implementation would do the job.That being said, there are a number of reasons you’d ...

Feed: CronJ. Author: prajval; Healthcare apps have changed the way hospitals function. They have brought technology to handle all the movements of the hospital, and the result has been positive and useful for both Hospitals and patients. With the help of these Healthcare apps, the burden of waiting in the hospital for hours to meet the doctor has come to an end as the patient can book an appointment with the help of the Apps.We have hundreds of apps to book appointments and to consult doctors online, but we have very few apps for Bed Management in hospitals. Thus, CronJ ... Read More

Feed: Planet MySQL; Author: MySQL Performance Blog; Percona Server for MySQL 8.0.19 includes the experimental simple LDAP authentication plugin, which allows for direct authentication using an LDAP server. Similarly to the data masking plugin added in 8.0.18, this plugin was also added as a community contribution from Francisco Miguel Biete.Authenticating with LDAPIn earlier versions, Percona Server for MySQL supported the built-in authentication mechanism of MySQL and also included a port of the PAM plugin from MySQL enterprise.As LDAP servers can be configured as backends for PAM, this already provided a way to authenticate SQL users using LDAP, by adding PAM ...

Feed: Planet MySQL; Author: MySQL Performance Blog; This is a three-part blog series that focuses on dealing with an unexpected high traffic event as it is happening. Part one of this series talked about the first six things you can do, and in part two, we will be discussing numbers seven through twelve.7. Get More MemoryComplexity: LowPotential Impact: HighIf your data does not fit into memory well, your MySQL performance is likely to be severely limited. If your data already fits in well, adding even more memory will not provide any performance improvements.Even when you’re running on very fast storage, ... Read More
