Database Lab Engine - Thin database clones for faster development

The Database Lab Engine is an open-source experimentation platform for PostgreSQL databases. Instantly create full-size clones of your production database and use them to test your database migrations, optimize SQL, or deploy full-size staging apps.

Thin cloning is possible due to copy-on-write capabilities provided by either ZFS filesystem or LVM2. As an example, cloning of 10 TiB PostgreSQL database takes less than 2 seconds when a single user is using the Database Lab Engine instance, and up to 30 seconds when 15 users are working with it at the same time.
