How to create a private on-demand PostgreSQL instance accessible only| /dev/posts/
Postgres creates an execution plan for how to retrieve the data you're asking for in a query. The execution plan is based in part on statistics from your data and indexes it has available. Just the right index and a bit of query tuning can have a huge payoff in performance gains that your users will notice.| Frontend Masters Boost RSS Feed
This Part 1 (of a 2-part series) is a practical, hands-on, applicable approach to database indexes. We’ll cover what B Trees are with a focus on deeply understanding, and internalizing how they store data on disk, and how your database uses them to speed up queries. This will set us up nicely for part 2, […]| Frontend Masters Boost RSS Feed

On a recent project at Hashrocket, we had to use dblink in production as part of our set up for communicating with a legacy database. While our overall experience was positive, we had a couple of hiccups along the way. Let's talk about the lessons we learned! What is dblink? dblink is a Postgres command that allows you to connect to and execute queries on a remote database. There are a number of dblink-related commands in Postgres depending on your use case (from dblink_connect to dblink_exec...| Hashrocket

AWS RDS supports blue/green deployments to support database maintainence. In a blue/green deployment, you have one production (blue) and one staging (green) database. You can safely make changes to the green instance without affecting production and promote it to be the main instance. When you enable blue/green updates, Pulumi will temporarily set up a blue/green deployment for the duration of the update to minimize downtime. There are many benefits to using blue/green deployments for updates...| Pulumi Blog
