DLE 2.5: Better data extraction for logical mode and configuration improvements

note

Action required to migrate from a previous version. See Migration notes.

The Database Lab Engine (DLE) is an open-source technology that enables thin cloning for PostgreSQL. Thin clones are exceptionally useful when you need to scale the development process. DLE can manage dozens of independent clones of your database on a single machine, so each engineer or automation process works with their own database provisioned in seconds without extra costs.

DLE 2.5 significantly expands the capabilities of automatic preparation of snapshots directly from managed database services, as well as from logical dumps, namely:

  • restoring of multiple databases
  • various pg_dump output formats and file compression formats

Since version 2.5, it becomes possible to reset the clone's database state to a specific snapshot if multiple snapshots are available. See DLE CLI reference. There is also a new option for the reset command, --latest, that allows resetting to the latest available state not knowing the snapshot name. This can be very useful in situations when a clone lives long, occupying a specific port, and some applications (e.g., analytical tools) are configured to work with it – users can periodically switch to the freshest database state without a need to reconfigure their applications.

All new restore features are also already available in the Terraform module (currently works with AWS only).

Additionally, this release has a lot of improvements and fixes. Read the full changelog.
