# To disable this behavior, set the environment variable # by acquiring a temporary license from Cockroach Labs in the background. # This demo session will attempt to enable enterprise features # You are connected to a temporary, in-memory CockroachDB cluster of 1 node. # Welcome to the CockroachDB demo database! We’ll run the command with the -empty flag so the we don’t run into any conflicts loading the CodeTriage schema later. Next, we’ll use the cockroach demo command to create a single-node CockroachDB cluster. How do you install CockroachDB?įirst, install CockroachDB per the install guide. To switch to using CockroachDB, we’ll first need to install and configure CockroachDB. In this example, we’re going to change the CodeTriage Rails app so it uses CockroachDB instead of PostgreSQL.Īfter following the CodeTriage contributing guide to get the app running locally, the app will be ready to talk to PostgreSQL. So how do we use CockroachDB with Rails? Since I like learning by example, let’s configure an existing Rails app to use CockroachDB. It also uses the PostgreSQL wire protocol so you can use it almost anywhere you’d use PostgreSQL. Glad you asked! CockroachDB, built by Cockroach Labs, is a database that’s designed to be scalable and highly available. ![]() If you’re with me so far, then it should come as no surprise that it’s just as easy to use CockroachDB with Rails! □ What’s a CockroachDB?

Ruby/PgSQL error on Rails start : cannot load such file - pg_ext (LoadError)Įach time, the gem installs correctly. I have tried all of the suggestions in the previous post I wrote about this problem with my first app. I have tried uninstalling and reinstalling pg. Make sure that gem install pg -v '0.18.4' succeeds before bundling. My post about the problem the first time is here: Installing PG gem on OS X - failure to build native extensionĪn error occurred while installing pg (0.18.4), and Bundler cannot continue. ![]() I"m now having the same problem I had the first time around in getting the pg database setup, but none of the solutions offered for the first problem are working this time.
