Feed: Planet MySQL; Author: Oracle MySQL Group; MySQL Query Optimization is usually simple engineering. But seeking information about how to tune queries is treated on many web reference sites like some Harry Potter-ish spell casting. There are simple tips you need to be aware of to get the best of your queries ... Read More

Feed: Planet PostgreSQL. Jupiter's moon Io. Credit: ALMA (ESO/NAOJ/NRAO), I. de Pater et al.; NRAO/AUI NSF, S. Dagnello; NASA/JPL/Space Science InstituteSQL query optimization is challenging for those who have just started working with PostgreSQL. There are many objective reasons for this, such as:the difficulty of the field of system performance in general,lack of good "playground" environments where people can experience how databases work at a larger scale,lack of certain capabilities in Postgres observability tools that are still developing (though, at a good pace),insufficiency of good educational materials.All these barriers are reasonable. They limit the number of engineers possessing well-developed Postgres ... Read More

Feed: Recent Announcements. AWS Trusted Advisor now supports new recommendations that help you simplify your SQL Server optimization on Amazon EC2. The checks inspect your SQL Server workloads and automatically lists your SQL Server instances that need optimization. You can then take recommended actions to reduce costs and improve security. You can find the details of the three checks below. 1. Amazon EC2 Instances with Microsoft SQL Server End of Support - Checks the SQL Server versions for Amazon EC2 instances and alerts you if the versions are near or have reached the end of support. For example, SQL Server ... Read More

Feed: Recent Announcements. AWS Lake Formation is excited to announce the general availability of three new capabilities that simplify building, securing, and managing data lakes. First, Lake Formation Governed Tables, a new type of table on Amazon S3, that simplifies building resilient data pipelines with multi-table transaction support. As data is added or changed, Lake Formation automatically manages conflicts and errors to ensure that all users see a consistent view of the data. This eliminates the need for customers to create custom error handling code or batch their updates. Second, Governed Tables monitor and automatically optimize how data is stored so ... Read More

Feed: Recent Announcements. Today we announce the general availability of Syne Tune, an open-source Python library for large-scale distributed hyperparameter and neural architecture optimization. It provides implementations of several state-of-the-art global optimizers, such as Bayesian optimization, Hyperband and population-based training. Additionally, it supports constrained and multi-objective optimization, and it allows users to bring their own global optimization algorithm. With Syne Tune users can run hyperparameter and neural architecture tuning jobs locally on their machine or remotely on Amazon SageMaker by changing just one line of code. The former is a well-suited backend for smaller workloads and fast experimentation on local ... Read More

Feed: Top Blog Posts. Author: Vincent Granville. In this series, we discuss a technique to find either the minima or the roots of a chaotic, unsmooth, or discrete function. A root-finding technique that works well for continuous, differentiable functions is successfully adapted and applied to piece-wise constant functions with an infinite number of discontinuities. It even works if the function has no root: it will then find minima instead. In order to work, some constraints must be put on the parameters used in the algorithm, while avoiding over-fitting at the same time. This would also be true true anyway for ... Read More
