DLE 2.2 and Joe 0.9

About Database Lab Engine#

The Database Lab Engine (DLE) is an open-source experimentation platform for PostgreSQL databases. The DLE instantly creates full-size thin clones of your production database which you can use to:

  1. Test database migrations
  2. Optimize SQL queries
  3. Deploy full-size staging applications

The Database Lab Engine can generate thin clones for any size database, eliminating the hours (or days!) required to create “thick” database copies using conventional methods. Thin clones are independent, fully writable, and will behave identically to production: they will have the same data and will generate the same query plans.

Database Lab Engine 2.2.0#

Database Lab Engine (DLE) 2.2.0 further improves support for both types of PostgreSQL data directory initialization and synchronization: “physical” and “logical”. Particularly, for the “logical” type (which is useful for managed cloud PostgreSQL such as Amazon RDS users), it is now possible to setup multiple disks or disk arrays and automate data retrieval on a schedule. This gracefully cleans up the oldest versions of data, without downtime or interruptions in the lifecycle of clones.
