We have just released open-source version 2019.2 of the Inmanta Orchestrator.
The big change in this release is the switch from MongoDB to PostgreSQL. When upgrading to 2019.2, please consult the documentation. By moving to PostgreSQL, we have roughly doubled the deployment performance.
A second big improvement is that the orchestrator can now report performance metrics, allowing operators to monitor the performance. To enable this, look at the documentation.
