I have seen many Linux Performance engineers looking at the “IOWait” portion of CPU usage as something to indicate whenever the system is I/O-bound. In this blog post, I will explain why this approach is unreliable and what better indicators you can use. Let’s start by running a little experiment – generating heavy I/O usage on the system: sysbench --threads=8 --time=0 --max-requests=0 fileio --file-num=1 --file-total-size=10G --file-io-mode=sync --file-extra-flags=direct
So many bad takes — What is there to learn from the Prime Video microservices to monolith story Excerpt from Serverless First deck first published in 2019 The Prime Video team published this story: Scaling up the audio/video monitoring service and reducing costs by 90% , and the internet piled in with opinions and bad takes, mostly missing the point.
In today's fast-paced digital world, application performance has become critical in delivering a seamless user experience.

Many MongoDB clusters use storage-level snapshots to provide fast and reliable backups. In this blog post, you’ll learn how to restore such a snapshot from a traditional VM-based sharded MongoDB cluster to a freshly deployed Percona Operator for MongoDB cluster on Kubernetes. Background story I recently worked with a company running a large four-shard MongoDB Enterprise Server database cluster on VMs on premises that decided to migrate to the Google Cloud Platform.
It’s hard to ignore the discussion around the Open Letter arguing for a pause in the development of advanced AI systems. Are they dangerous? Will they destroy humanity? Will they condemn all but a few of us to boring, impoverished lives? If these are indeed the dangers we face, pausing AI development for six months is certainly a weak and ineffective preventive.

In simpler terms, logical replication in PostgreSQL is a way to copy data from one database to another in a more flexible and customizable manner compared to physical replication. Instead of copying the entire database, logical replication focuses on replicating changes made to individual rows or transactions. To set up logical replication, you create a publication on the source database and a subscription on the target database.
Today at Google I/O 2023, it was announced that Interaction to Next Paint (INP) is no longer an experimental metric. INP will replace First Input Delay (FID) as a Core Web Vital in March of 2024.

Vendor lock-in. The term is inherently ominous, and a broad definition isn’t much cheerier. They both suggest limited or lost freedom. To determine whether that perception is warranted in the database software industry — and if so, how to avoid vendor lock-in pitfalls — let’s dig deeper. First, here’s a broad and common definition: Vendor lock-in means having to rely on one company for a product or service because switching to other options would be too costly in te
Kubecon is the most significant event focused on the Kubernetes ecosystem. It takes place once a year in North America, Europe, and Asia. It is a perfect opportunity to learn from experts, meet friends, grow your network, and attend talks at a varied technical level and meetings focused on CNCF communities. This time I attended Kubecon in Amsterdam.

The system design of the Presence Platform depends on the design of the Real-Time Platform. I highly recommend reading the related article to improve your system design skills. The original article was published on systemdesign.one website. What Is the Real-Time Presence Platform? The presence status is a key feature to make the real-time platform engaging and interactive for the users ( clients ).
When code breaks, our first move is carefully inspecting the call stack. It helps us find the needle in the haystack by understanding how, where, and why the failure occurred, including how we got there. However, in a message-based system, we no longer have a single call stack. We’ve exchanged it for a haystack of call stacks , which makes finding the needle (the root cause of the failure) even more difficult. ?
Batch request processing is a powerful technique used in web development to improve the performance of APIs. It allows developers to group multiple API requests into a single HTTP request/response cycle. In other words, a single API request from a client can be turned into multiple API requests to a set of backend servers, and the responses are aggregated into a single response to the client.
For reference: Checkout my previous article where I discuss connection pool high availability, " Connection Pool High Availability With CockroachDB and PgCat." Motivation The load balancer is a core piece of architecture for CockroachDB. Given its importance, I'd like to discuss the methods to overcome the SPOF scenarios.
As an increasing number of organizations transition to cloud-based infrastructures, data integration has emerged as a crucial component of the cloud migration process. Data integration encompasses integrating data from disparate sources into a consolidated perspective. The context of cloud migration pertains to the transfer of data from on-premise systems to cloud-based platforms while ensuring data consistency, accuracy, and usability.
Content Delivery Network (CDN) is not a new technology. In fact, it has been around for many years. Every internet user, knowingly or unknowingly, uses a CDN while watching a video, reading a newspaper, or enjoying a TV show. As CDN solutions become mainstream, organizations must choose the right CDN platform to seamlessly and securely serve content to end-users.
Development practices are constantly changing, and as testers, we must embrace change. One of the changes that we can experience is the move from monthly or quarterly releases to continuous delivery or continuous deployment. In addition, this move to continuous delivery or deployment offers testers the chance to learn new skills. A project that makes monthly or quarterly releases has a familiar rhythm, and the team builds toward the release date.
In this series of simulating and troubleshooting performance problems in Scala, let’s discuss how to make threads go into a blocked state. A thread will enter into a blocked state when it cannot acquire a lock on an object because another thread already holds the lock on the same object and doesn’t release it. Scala Blocked Thread Program Here is a sample program, which would make threads go into a blocked state.
This blog post is the first of a series of articles aimed to show a landscape of metrics and telemetry solutions possible to use in different Scala ecosystems, including some examples of APM solutions. I possibly won't cover all possible solutions or a combination of those but will try to cover the main one. Please, NOTE: this series is not going to compare telemetry as whole products between each other; instead, it focuses on how to use each telemetry framework in different Scala ecosystem and
