The best part is that we are also significantly expanding the free tier many of you already enjoy by increasing the storage to 25 GB and throughput to 200 million requests per month. More than a decade ago, Amazon embarked on a mission to build a distributed system that challenged conventional methods of data storage and querying.

Named after the Greek god who brought fire down from Mount Olympus, Prometheus metrics have been transforming observability since the project’s inception in 2012. But often, we use additional services and solutions within our environment for backups, storage, networking, and more. What is Prometheus?

DynamoDB has come a long way in the 5 years since we announced its availability in January 2012. As we said at the time, DynamoDB was a result of 15 years of learning in the area of large scale non-relational databases and cloud services. DynamoDB was the first service at AWS to use SSD storage. Fully managed cache for DynamoDB.

This blog was originally published in January 2012 and was updated in June 2023. A full backup is a comprehensive data backup strategy that involves creating a complete, exact copy of all data and files in a database. In order to implement effective full backups of your database, you must follow some best practices.

Before we dive into the differences between MariaDB and MySQL, we will provide a thorough examination of each relational database management system (RDBMS). While originally designed to be a drop-in replacement for MySQL, it evolved into its own distinct database management system and is now maintained and supported by the MariaDB Foundation.

In SQL Server 2012, grouped (vector) aggregation was able to use parallel batch-mode execution, but only for the partial (per-thread) aggregate. Columnstore storage. To understand this, it is necessary to first review how columnstore storage works at a high level: A compressed row group contains a column segment for each column.

To provide some coherence to the music, I decided to use Taylor Swift songs since her discography covers the time span of most papers that I typically read: Her main albums were released in 2006, 2008, 2010, 2012, 2014, 2017, 2019, 2020, and 2022. This choice also inspired me to call my project Swift Papers.
