Grouped aggregations are a core part of any analytic tool, creating understandable summaries of huge data volumes. Apache Arrow DataFusion’s parallel aggregation capability is 2-3x faster in version 28.0.0 for queries with a large number (10,000 or more) of groups.
Not to be confused with the popular children’s TV character, DORA is a new EU regulation for the financial sector, which stands for the Digital Operational Resilience Act. DORA became law on 16 January 2023 and will start to apply from 17 January 2025, so it’s crucial that senior executives in the financial sector, such as Chief Risk Officers and Chief Information Security Officers, understand its implications and prepare for compliance from day one.
It’s no secret that anyone can download our open source software and run it, because — once more with feeling — open source is in our DNA. But it can be hard to set up and configure a whole stack from scratch, which is why we offer Grafana Cloud as a fully managed observability platform.
At Kubecon 2023 in Amsterdam, Azure made several exciting announcements and introduced a range of updates and new options to Azure-CNI (Azure Container Networking Interface). These changes will help Azure Kubernetes Services (AKS) users to solve some of the pain points that they used to face in previous iterations of Azure-CNI such as IP exhaustion and big cluster deployments with custom IP address management (IPAM).
Prometheus is an increasingly popular tool in the world of SREs and operational monitoring. Based on ideas from Google’s internal monitoring service (Borgmon), and with native support from services like Docker and Kubernetes, Prometheus is designed for a cloud-based, containerized world. As a result, it’s quite different from existing services like Graphite. Starting out, it can be tricky to know where to begin with the official Prometheus docs and the wave of recent Prom content.
Using Prometheus and Grafana together is a great combination of tools for monitoring an infrastructure. In this article, we will discuss how Prometheus can be connected with Grafana and what makes Prometheus different from the rest of the tools in the market. MetricFire's product, Hosted Graphite, runs Graphite (a Prometheus alternative) with Grafana dashboards for you so you can have the reliability and ease of use that is hard to get while doing it in-house.
Understanding the state of your systems and their underlying infrastructure at all times is paramount for ensuring the stability and reliability of your services. Up-to-date information about the performance and health of your deployments not only helps your team react to issues in real time, but it also gives them the security to make changes with confidence and to safely forecast system failures or performance hiccups even before they occur.
In today's digital landscape, optimal web application performance is crucial for business success. Slow loading times, unresponsive pages, and inefficient code can drive away users and harm your reputation. This makes monitoring web app performance extremely important to prevent them and to provide a smooth user experience. Sitespeed, a powerful web performance monitoring framework, analyzes metrics like page load time, resource usage, and user interactions to identify performance bottlenecks.
