Feed: Planet PostgreSQL. Citus 11.0 is here! Citus is a PostgreSQL extension that adds distributed database superpowers to PostgreSQL. With Citus, you can create tables that are transparently distributed or replicated across a cluster of PostgreSQL nodes. Citus 11.0 is a new major release, which means that it comes with some very exciting new features that enable new levels of scalability. The biggest enhancement in Citus 11.0 is that you can now always run distributed queries from any node in the cluster because the schema & metadata are automatically synchronized. We already shared some of the details in the Citus ... Read More

Feed: Planet PostgreSQL. When Disco was the hot new music, the people who built database management systems based their praxis around the then-correct assumption that hardware was extremely expensive, and hence that procuring things like more storage, let alone more machines on which they would run, could be counted on to require significant capital resources. This could only happen on the time scale of quarters, even if it was deemed worthwhile to fight the fights needed to procure them.The above conditions informed the practice of hardening single nodes against failure without adding significant hardware resources in the process. This practice ... Read More

Feed: Planet MySQL; Author: Michael McLaughlin; While I blogged about how to setup Node.js and MySQL almost two years ago, it was interesting when a student ran into a problem. The student said they’d configured the environment but were unable to use Node.js to access MySQL. The error is caused by this import statement: const mysql = require('mysql') The student got the following error, which simply says that they hadn’t installed the Node.js package for MySQL driver. internal/modules/cjs/loader.js:638 throw err; ^   Error: Cannot find module 'mysql' at Function.Module._resolveFilename (internal/modules/cjs/loader.js:636:15) at Function.Module._load (internal/modules/cjs/loader.js:562:25) at Module.require (internal/modules/cjs/loader.js:692:17) at require (internal/modules/cjs/helpers.js:25:18) at ...

Feed: Recent Announcements. To deploy Lambda functions using Node.js 16, upload the code through the Lambda console and select the Node.js 16 runtime. You can also use the AWS CLI, AWS Serverless Application Model (AWS SAM) and AWS CloudFormation to deploy and manage serverless applications written in Node.js 16. Additionally, you can also use the AWS-provided Node.js 16 base image to build and deploy Node.js 16 functions using a container image. To migrate existing Lambda functions running earlier Node versions, review your code for compatibility with Node.js 16 and then update the function runtime to Node.js 16 ... Read More

Feed: AWS Compute Blog. Author: James Beswick. This post is written by Dan Fox, Principal Specialist Solutions Architect, Serverless. You can now develop AWS Lambda functions using the Node.js 16 runtime. This version is in active LTS status and considered ready for general use. To use this new version, specify a runtime parameter value of nodejs16.x when creating or updating functions or by using the appropriate container base image. The Node.js 16 runtime includes support for ES modules and top-level await that was added to the Node.js 14 runtime in January 2022. This is especially useful when used with Provisioned Concurrency to reduce cold start ... Read More

Feed: Planet PostgreSQL. Recently I worked on a web app designed for tracking, editing, and reporting on archaeological survey data. When I joined the project, it used React on the front-end, Node.js on the back-end, GraphQL as the API interface, and MongoDB as the database. For the most part, this architecture and choice of technology worked well, and I was quickly able to make meaningful contributions to the app both in the user interface and in the backend. However, after a while, things started to get difficult and we began to consider why we were using MongoDB, and what might ... Read More

Feed: Recent Announcements. AWS Lambda functions using the Node.js 14 runtime now support code packaged as ECMAScript modules, allowing Lambda customers to consume a wider range of JavaScript packages in their Lambda functions. In addition, Lambda customers can now take advantage of ‘top-level await’, a Node.js 14 language feature. When used with Provisioned Concurrency, this improves cold-start performance for functions with asynchronous initialization tasks. For more information, see the blog post Using Node.JS ES Modules and Top-Level Await in AWS Lambda. ECMAScript (ES) modules are a packaging format for JavaScript code, used to publish JavaScript code libraries so they can be ... Read More

Feed: AWS Compute Blog. Author: James Beswick. This post is written by Dan Fox, Principal Specialist Solutions Architect, Serverless. AWS Lambda now enables the use of ECMAScript (ES) modules in Node.js 14 runtimes. This feature allows Lambda customers to use dependency libraries that are configured as ES modules, or to designate their own function code as an ES module. It provides customers the benefits of ES module features like import/export operators, language-level support for modules, strict mode by default, and improved static analysis and tree shaking. ES modules also enable top-level await, a feature that can lower cold start latency ... Read More
