Build a Rails App with ActiveRecord and CockroachDB

*Guest post alert! Marla and Ali worked with the Cockroach Labs team to get the ActiveRecord CockroachDB Adapter ready for Rails 5.2 and beyond! Their work with Cockroach Labs is done, but the adapter lives on. This blog post was originally shared on their blog at Test Double.* -– When I work in Rails apps, I don’t find myself worrying too much about the database. Since Rails natively supports popular databases like MySQL and PostgreSQL, I usually only need to make a few config changes to get an application’s database up and running.
