Overview

A Matillion ETL project is a logical grouping of configuration settings and resources—such as jobs—required to use Matillion ETL. When users first log in to their Matillion ETL instance, they will be required to click Confirm in the Product Improvement Metrics dialog, and then they must create a project if no existing projects are available to select.

To create a new project, there are two routes:

  1. The first route is found in the Join Project dialog, which will appear automatically upon first loading an instance.
  2. The second route can be accessed by clicking Project, then clicking Switch Project, and then (for both methods) clicking Create Project.

There are no practical limits to the number of projects you can create. However, only one project is used by the client session at a time, and each project must have a unique name.

Note

These instructions assume you have already successfully launched a Matillion ETL instance.

Cluster states

In Matillion ETL, each cluster in the Cluster drop-down menu is assigned a state, with a Databricks equivalent. See the table below for more information:

Matillion ETL Databricks
STOPPED Terminated
STARTING Pending
RUNNING Running

When a cluster is not running, databases won't be retrieved, and the Database drop-down menu won't offer any selections. Attempting to select a database on a cluster that displays a STOPPED state will automatically trigger a cluster to start, but it can take a few minutes for the intended cluster to move from STOPPED to RUNNING, and it will be in the STARTING state during this time.

Clicking Back and returning to Delta Lake Defaults will refresh and update the state of the clusters, and is a required action to show when a cluster has transitioned from STOPPED to Pending, or RUNNING. Refreshing and updating the state of the clusters will also reload the Database drop-down menu.


Next steps

When you first login to Matillion ETL, we recommend you replace your default username and password with your own secure login credentials. For more information about changing these credentials, read User Configuration in the Admin Menu.
