Database Lab Engine (DLE) is an open-source (AGPLv3) technology that allows blazing-fast cloning of Postgres databases of any size in seconds. This helps solve many problems such as:

• build dev/QA/staging environments involving full-size production-like databases,
• provide temporary full-size database clones for SQL query analysis optimization (seeJoe bot),
• automatically verify database migrations (DB schema changes) and massive data operations in CI/CD pipelines to minimize risks of downtime and performance degradation.

As an example, cloning a 10 TiB PostgreSQL database can take less than 2 seconds.
