Feed: Recent Announcements. Amazon Elastic Container Service (Amazon ECS) now supports Amazon ECS Exec and Amazon Linux 2 for workloads running on-premises with Amazon ECS Anywhere. ECS Exec makes it easier for customers to troubleshoot errors, collect diagnostic information, interact with processes in containers during development, and get “break-glass” access to containers to debug critical issues encountered in production. With Amazon Linux 2, customers can now easily use the same AWS-secured operating system on-premises and in the cloud for development and testing. AWS customers running containerized applications on-premises often need to run commands on a subset of containers. With Amazon ECS ... Read More

Feed: Planet PostgreSQL. This blogpost is about the internals of a linux pread (pread64) call, which both Postgresql and YugabyteDB are using. In the previous post I've set the stage of the mandatory steps and thoughts for understanding IO performance. The essence is that there are several layers that an IO call (pread64()) has to cross from user land before the actual IO is executed on the physical device. The previous post described the execution flow of a read call that got serviced by the linux page cache. This part takes a look into what happens when physical does actually ... Read More

Feed: Planet PostgreSQL. Reading data is a fundamental property of many applications, especially for databases, because their function is to manage data, and use a disk to persist data and read the stored data. A lot of people would take the database's latency measurement, or the latency measured by a tool and take that as the fundamental IO speed. This blogpost is about what that figure means, and to help you in diagnose and think about that latency. A fundamental property that MUST be known is whether the read call is done buffered (using page cache of linux) or unbuffered ... Read More

Feed: Planet MySQL; Author: Jean-François Gagné; I created the first draft of this post many years ago.  At that time, I was working with physical servers having 192 GB of RAM or more.  On such systems, doing memory pressure tests with MySQL is complicated.  I used a trick to simulate a Linux server with less RAM (also works with vms, probably not with Kubernetes or containers).  I recently needed the trick again and as I will refer to it in a future post, now is a good time to complete and publish this.  TL&DR: huge pages... Let's say you want ... Read More

Feed: Recent Announcements. AWS App2Container (A2C) now supports containerization and deployment of .NET applications running on Linux. With this release, customers can use A2C to detect the .NET Core runtime version (.NET Core 3.1, .NET 5, .NET 6) and containerize the application using the corresponding runtime base images. Customers can take advantage of cost and performance benefits offered by Linux containers. Customers can continue to deploy these containerized applications to their choice of container platforms, Amazon Elastic Container Service (Amazon ECS), Amazon Elastic Kubernetes Service (Amazon EKS), AWSFargate, and AWS App Runner using A2C ...
