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: Actian. Author: Pradeep Bhanot. There are times when financial markets trend up. There are times that markets trend down.  And then there are times that the markets go crazy and the only thing predictable is volatility. When markets encounter these volatile periods, financial services companies become highly reliant on data analytics to determine where the real market forces are coming from and determine how best to react. There are five key analytics capabilities that financial services companies need to perform effectively in a volatile market environment.Connected Data The more data you have available to analyze, the more accuracy you ...

Feed: Planet MySQL; Author: Krunal Bauskar; By and large this would be a topic of interest for most of us including me when I started to explore this space. Before we dwell into the numbers let’s first understand some basic differences between 2 architectures. Beyond being CISC and RISC let’s look at the important differences from MySQL perspective. Strong vs Weak memory model (weak memory model needs proper memory barrier while writing lock-free code). Underlying hardware specific specialized instructions. For example: both now support crc32c hardware instructions but being low-level they are different ways to invoke them. For more differences ... Read More

Feed: Actian. Author: Pradeep Bhanot. Healthcare is a data-driven industry with data analytics needs that make “big data” seem tiny.  For healthcare companies to operate efficiently, they need a high-power data engine to crunch the numbers, analyze the data, and get it into the hands of decision-makers quickly.  The healthcare industry is the epitome of business agility, and data analytics is what makes that possible. Here are four examples of how healthcare analytics can help healthcare companies improve operational efficiency.Diagnosis and Patient Care If a patient walks into a clinic with a fever, dry cough, and respiratory symptoms, do they ...

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: Redis Labs. Author: Pieter Cailliau. Redis is a noSQL database that enables users to store a variety of data in a variety of data structures. We saw a need for our customers to create highly connected data and derive insight by using graph technology. Originally released in 2018, RedisGraph is the result of that effort. RedisGraph is based on a unique approach and architecture that translates the Cypher query language to matrix operations executed over a GraphBLAS-based engine. By using sparse matrices to represent graphs and the power of GraphBLAS to process them, RedisGraph delivers a fast and efficient ... Read More

Feed: The Connector by Workato. Author: Pamela Seaton; While Business Technologists are increasingly being recognized as changemakers in an organization, 91% of them are frustrated with their jobs. This could be due to the fact that despite being hired to drive organizational efficiency, they are often hampered by: The speed at which they can deliver projects to lines of business (HR, IT, Sales, etc.) (62%)The “time it takes to get things done using tools at my disposal” (44%)Stuck putting out fires rather than building systems (42%)Lack of alignment (37%)Given this changing landscape and the shifting needs of the lines of ...

Feed: Planet PostgreSQL. By design, the out of the box configuration for PostgreSQL is defined to be a "Jack of All Trades, Master of None". The default configuration for PostgreSQL is fairly painstakingly chosen to ensure that it will run on every environment it is installed, meeting the lowest common denominator resources across most platforms.Because of this, it's always recommended that one of the first actions performed once an install of PostgreSQL is completed, would be to tune and configure some high-level settings. There are four high-level settings which will be discussed here: shared_buffers,  wal_buffers,  effective_cache_size, and maintenance_work_mem. Let's begin with shared_buffers ... Read More
