For example, cloning a 1 TiB PostgreSQL database takes ~10 seconds. Dozens of independent clones are up and running on a single machine, supporting lots of development and testing activities, not increasing costs for hardware.

Thin cloning is fast because it uses Copy-on-Write (CoW). DLE supports two technologies to enable CoW and thin cloning: ZFS (default) and LVM.

With ZFS, Database Lab Engine periodically creates a new snapshot of the data directory and maintains a set of snapshots, cleaning up the old and unused ones. When requesting a new clone, users can choose which snapshot to use.

If you are actively using DLE at work, think about where you could mention it. The best way of mentioning it is using graphics with a link. Brand assets can be found in the ./assets folder. Feel free to put them in your documents, slide decks, application, and website interfaces to show that you use DLE.
