When you're working with DynamoDB, one of the most critical things you need to keep an eye on is throttling. If you're not careful, throttling can severely impact your database's performance. It’s not just about slower response times—throttling can lead to system failures or unexpected downtime if not addressed properly.

Cardinality refers to the number of unique values in a dataset column. A column with many distinct values—like a user ID or timestamp—has high cardinality, while a column with limited distinct values—like a boolean flag (true/false) or a category with a few possible options—has low cardinality. For example, consider a database of an e-commerce platform.

Redgate's new book, 'Introduction to PostgreSQL for the data professional', is now available for free download. Hear from authors Ryan Booz & Grant Fritchey about their inspiration for the book and the challenges they faced along the way. While the documentation around PostgreSQL is detailed and technically rich, finding a simple, clear path to learning what it is, what it does, and how to use it can be challenging.

In case you haven’t heard about it yet, FOSDEM (Free and Open Source Software Developers’ European Meeting) is a huge, free, gathering for open-source software enthusiasts that happens every February in Brussels, Belgium. It’s a non-profit event put together by the community, and it’s one of the biggest of its kind - we’re talking about around 10,000 people from all over the world coming to hang out and talk about all things open source.

We are excited to introduce a new version of SecureBridge 10.7 – a suite of client and server components for SSH, SFTP, FTPS, HTTP/HTTPS, SSL, WebSocket, and SignalR protocols – packed with enhanced security, optimized performance, and extended functionality for secure data transmission.

Redis is a highly efficient, versatile in-memory data store that is commonly utilized in modern applications. However, like any technology, it is not without its challenges, particularly when it comes to managing connections. By systematically reviewing Redis logs, you can diagnose and resolve these problems effectively. This blog provides an overview of Redis logs, explores their importance, and highlights how log management tools can simplify troubleshooting.

Azure Flexible Server joins the suite of PostgreSQL hosting platforms supported by Redgate Monitor, which also includes Linux hosts or VMs, Amazon RDS and Aurora. Our goal is to provide you with a single-pane-of-glass view of your entire PostgreSQL estate, whether it’s running in Azure, AWS, or on-prem, ensuring simpler troubleshooting, better insights, and faster performance tuning.

High-traffic applications demand speed, reliability, and scalability, making Redis a top choice for tasks like caching and real-time analytics. However, as traffic grows, ensuring Redis operates at peak performance requires effective monitoring. By tracking key metrics, addressing bottlenecks, and optimizing resource use, Redis monitoring plays a vital role in maintaining stability and scalability.

Imagine your PostgreSQL database slowing down unexpectedly, causing delayed queries, application timeouts, and frustrated users. In a data-driven world, database performance issues can lead to downtime, lost revenue, and poor user experience. PostgreSQL monitoring tools help detect and resolve performance bottlenecks, ensuring optimal database health, efficient query execution, and high availability.

What happens if we put OpenTelemetry, Prometheus 2.x, Prometheus 3.x, and vmagent together for comparison in scraping and pushing data to remote storage?

PostgreSQL is a beast when it comes to handling data, but if you're running an instance that needs to be accessed remotely, securing it with SSL is non-negotiable. Without SSL, your database connection is essentially an open book for anyone snooping on the network. Let’s lock it down with properly signed certificates!

So, you’ve got a PostgreSQL database packed with juicy data, and you want to turn those raw numbers into slick, interactive Grafana dashboards? Good call! Grafana’s PostgreSQL datasource is like the secret handshake that lets you visualize your data in style—no extra ETL magic required. In this guide, we’ll walk through getting PostgreSQL and Grafana to play nice, covering everything from connection settings to query tuning.
