Adoption of IoT (Internet of Things) is increasing across various industries, in government sectors, and in consumers’ day-to-day life. Moreover, the enterprises are rapidly migrating or developing and rolling out their IoT-enabled apps into the mobile app market.
In a MySQL hosting replication setup, the parameter Seconds_Behind_Master (SBM), as displayed by the SHOW SLAVE STATUS command, is commonly used as an indication of the current replication lag of the slave. In this blog post, we examine how to understand and interpret this value in various situations. Possible Values of Seconds Behind Master. The value of SBM, as explained in the MySQL documentation , depends on the state of the MySQL slave in general, and the states of MySQL slave SQL_THREAD
When it comes to network performance, there are two main limiting factors that will slow you down: bandwidth and latency. Bandwidth is defined as…. …the maximum rate of data transfer across a given path. Generally speaking, increased bandwidth is only particularly useful when you’re transferring or downloading large files. If you’re streaming video, the difference between a 2Mb 1 connection and a 20Mb connection will surely be appreciated.
Poor performance leads to exclusion. When we create heavy sites we limit what users can access our content. Those with more powerful devices and better network will get sites loaded faster. Those with older devices and slower network will need to wait more. Why performance is important Study after study shows how slowing sites down results in less engagement, less time on the site and a general decrease in key business metrics.
One question I’ve seen posed a few times in the past several months is whether performance really is a moral or ethical concern, or if that’s all heavy-handed exaggeration. It’s a fair question, I suppose. Advocates of any technique or technology can be a bit heavy-handed when it suits them if they’re not being careful–myself included.
This post was written by Wendy Dessler of The Blog Frog. Database-as-a-Service (DBaaS) is quickly gaining in popularity across the tech world. These software platform solutions helps users easily manage their database operations without having to really understand any of the abstractions. This allows developers, DBA’s and DevOps engineers to quickly automate their backups, create new SQL and NoSQL clusters, and monitor the performance of their databases for their application without requir
Everyone talks about transformation these days, but the term is used so loosely that it’s begun to lose all meaning. I recently wrote a blog post suggesting that the ultimate test of transformation is whether the caterpillar became a butterfly – is it so different that it’s unrecognizable? That’s a useful metaphor, but many have asked me to make it more tangible in the world of institutions.

Robo 3T (formerly Robomongo) is a popular desktop graphical user interface (GUI) for your MongoDB hosting deployments that allows you to interact with your data through visual indicators instead of a text-based interface. This open source tool has cross-platform support and actually embeds the mongo shell within its interface to provide both shell and GUI-based interaction.
At the Linux Plumber's conference there were at least 24 talks on eBPF. It has quickly become not just an invaluable technology, but also an in-demand skill. Perhaps you'd like a new year's resolution: learn eBPF! eBPF should stand for something meaningful, like Virtual Kernel Instruction Set (VKIS), but due to its origins it is extended Berkeley Packet Filter.
MongoDB is one of the most popular NoSQL databases on the market right now and is used heavily with Node.js development in particular. So what if you wanted to give MongoDB a spin and see what it’s all about? There are plenty of deployment options when it comes to using MongoDB. For example, I had recently written a tutorial titled, Developing a RESTful API with Node.js and MongoDB Atlas which focused on the MongoDB cloud solution called Atlas.
Prior to my Automation Guild conference each year, I survey the community about the issues they're struggling with. I also speak with many testing thought leaders on my weekly Test Talks podcast.
Have you been experiencing slow MySQL startup times in GTID mode? We recently ran into this issue on one of our MySQL hosting deployments and set out to solve the problem. In this blog, we break down the issue that could be slowing down your MySQL restart times, how to debug for your deployment, and what you can do to decrease your start time and improve your understanding of GTID-based replication.
I perceive that fear is becoming pervasive and increasingly intense around the world. When I share this perception with others, I often get the response: “What fear? I don’t know many people who are afraid.”. That’s part of the problem. The fear is often not visible unless we know where and how to look for it. Why is that the case? Emotions are suspect As I’ve written elsewhere , our institutions are organized on a scalable efficiency model that views emotions as deeply suspect.
PALO ALTO, Calif., January 24, 2019 – ScaleGrid , a rising leader in the Database-as-a-Service (DBaaS) space, has just announced support for Redis Clusters on their fully managed Redis hosting plans. Redis Cluster is the native sharding implementation available within Redis, an open-source in-memory data structure project, that allows you to automatically shard across multiple Redis nodes without having to rely on external tools and utilities.

You may not think about it often, but the Internet uses a colossal amount of electricity. This electricity needs to be produced somewhere. In most countries, this means the burning of fossil fuels.
I’ve recently written several tutorials around GraphQL and there are more to come. However, most of these tutorials, including my eBook and video course, Web Services for the JavaScript Developer , have focused on the backend side of things and less of the frontend side of things. Knowing how to create a GraphQL powered API is great, but what if you need to query it from a client facing application?
Establishing a whole-team approach to testing in all phases of the software development lifecycle can be challenging. Even when testers use development-centric languages and IDEs to create automated tests, many developers still resist the notion of having to test their own code.

Yesterday there was a bit of a heated discussion around a WebKit issue that suggested putting a limit on the amount of JavaScript a website can load. In the issue, Craig Hockenberry makes the case that enforcing a limit on the amount of JavaScript would provide a sort of “meet me in the middle” solution for users currently using content blockers.
I’ve written quite a bit of content around developing a GraphQL API with various programming technologies such as Node.js, Golang, and Java. Heck, I even wrote an eBook on the subject titled, Web Services for the JavaScript Developer. However, I haven’t really produced any content around interacting with those APIs using modern frameworks and client facing technologies, only cURL and Postman.

For a very long time – since when multiple CPU cores were commonly available – I dreamed about MySQL having the ability to execute queries in parallel. This feature was lacking from MySQL, and I wrote a lots of posts on how to emulate parallel queries in MySQL using different methods: from simple parallel bash script to using Apache Spark to using ClickHouse together with MySQL.
Introducing The Component-Based API. Introducing The Component-Based API. Leonardo Losoviz. 2019-01-21T13:00:21+01:00. 2019-04-29T18:34:58+00:00. This article was updated on January 31, 2019 to react to readers’ feedback. The author has added custom-querying capabilities to the component-based API and describes how it works. An API is the communication channel for an application to load data from the server.
The concept of responsive web design has been around for a while, but all of the kinks have yet to be ironed out. The exponential proliferation of connected devices with varying software and technical capabilities has made it more and more difficult to cater web content to every single user. Furthermore, trying to accommodate everyone often leads to cluttered markup that negatively impacts performance.
Some may see testing as a fairly boring and static set of practices, but the leaders in this space know that it is a vibrant discipline that is constantly improving every year, thanks to exciting new techniques made possible by better automation tools and artificial intelligence.
I know I’ve mentioned this before, but I’ve recently started to get serious about my content production and deployment approach on The Polyglot Developer. My goal is to be able to write my tutorials in Markdown, push to GitLab, and have it automatically deployed as a Docker container on my production server. Being able to automate things and take advantage of Docker will definitely improve my productivity in the long term.

Parallel query execution is my favorite, non-existent , feature in MySQL. In all versions of MySQL – at least at the time of writing – when you run a single query it will run in one thread, effectively utilizing one CPU core only. Multiple queries run at the same time will be using different threads and will utilize more than one CPU core. On multi-core machines – which is the majority of the hardware nowadays – and in the cloud, we have multiple cores available for use.
In my previous post I talked about how loading scripts asynchronously reduces the impact of JavaScript resulting in a (much) faster user experience. But even when scripts are loaded async, the browser may still twiddle its thumbs for a second or more waiting for the first script to arrive. This delay can be decreased by using link rel=preload like this: Link rel=preload is useful for downloading any important resource more quickly, such as stylesheets that contain critical CSS, fonts that are us
The way a website is constructed can have a major impact on website speed performance, but developers often have a hard time keeping track of factors that cause slow page loads and other speed-related issues. The PageSpeed Module is one of several free Google tools designed to help assess and improve page load speed times. Unlike its more basic tools like PageSpeed Insights, you need some advanced technical skills to make the most of this PageSpeed service.

A common challenge with continuously deployed applications is that new and modified SQL queries are constantly being introduced to the application. Many companies choose to use a database monitoring system (such as PMM) to identify those slow queries. But identifying slow queries is only the start – what about actually optimizing them? In this post we’ll demonstrate a new way to both identify and optimize slow queries, by utilizing the recent integration of Percona Monitoring and Managemen
