The Amazon Relational Database Service (RDS) enables Amazon Web Services (AWS) customers to manage, operate, and scale their databases. A managed service, RDS provides seven database engines and multiple instance sizes and types for working with relational databases. AWS also claims RDS can match the performance, scalability, and availability of commercial databases for a tenth of the price. Is this true, and how much does Amazon RDS cost really? This guide explains how Amazon RDS pricing works.

While working on improving the Netdata PostgreSQL collector, we were monitoring our production PostgreSQL instance and something caught our attention immediately. The rows fetched ratio seemed really, really low for one particular database… there were missing indexes in PostgreSQL! Rows fetched ratio is the percentage of rows that contain data needed to execute the query (rows fetched), out of the total number of rows scanned (rows returned).

We all know we shouldn't use naughty words. Learn how to remove them from your streaming data using DataCater.

MongoDB is a cross-platform NoSQL database that uses JSON-like documents with optional schema to store data. It was designed for high availability, high performance for high-data persistance use cases, and automatic scaling. Of course, all with the right infrastructure in mind. It is usually a good choice for document-oriented use cases when you need quick prototyping or massive scale. With the massive scale comes massive traffic, though.

Redis is a popular open-source, in-memory data store used across industries by a variety of companies, including Github, Stack Overflow, Twitter and Netdata! Redis supports multiple use-cases including.

Since November 2021, Canonical and Microsoft have been offering a jointly supported Microsoft SQL Server on Ubuntu Pro solution. With this offering, you can set up an optimised configuration of SQL Server on Ubuntu in a few steps. As database professionals, we should ensure the highest possible standards for database security and availability. In this blog, we will detail how the combination of SQL Server and Ubuntu Pro can help you achieve those goals.

At Grafana Labs we run a lot of distributed databases. These distributed databases all make use of a hash ring in order to evenly distribute workloads across replicas of certain components. For a more detailed description of the architecture of our projects, check out our Mimir architecture docs.
