Introducing Visualized Turbine Applications

By  Sara Menefee

 8 Dec 2022

We are excited to announce—software developers can now visualize what is happening behind the scenes with their Turbine data apps deployed to the Meroxa Platform. The application visualization provides insight into runtime details of subcomponents the Meroxa Platform builds and configures based on the code written with Turbine. Including the directional flow of data.

We designed the Turbine Application Framework withdeveloper experience in mind. There's no need to learn a proprietary DSL (domain-specific language). Software developers can use their choice of supported programming language to build, test, and deploy robust data apps to process data streams. All while coexisting alongside an existing ecosystem of apps and services.

The Meroxa platform simplifies deployment by abstracting away the complexity required to build out and configure the various subcomponents necessary to run the data app and scale it dynamically, on demand, on our serverless architecture. The visualization aims to make this transparent.

Turbine Application Details

The app visualization lives in the application details page for your Turbine data apps. Here’s what you can expect.



A Source is a required Resource that contains the upstream data for the Turbine data app. There is a limitation of one Source per Turbine data app as we do not yet support multiple Sources. You may however include any number of APIs in your function to help enrich the data stream.

The Source node in the app visualization communicate the name, type, state, collection (e.g. table, collection, index, etc), and last updated timestamp.

Source details


A Function contains the custom code you have written using the process method. This is where you can transform or enrich data with any number of APIs from third-party platforms and services. The app visualization communicates the name, state, and last updated timestamp for the Function.

Function details


A Destination is a Resource where data will be sent from the Turbine data app downstream. You may leverage any number of Destinations, or none at all. It’s up to you.

Destination nodes in the app visualization communicate the name, type, state, collection (e.g. table, collection, index, etc), and last updated timestamp.

Destination details

Data Flow

Between each node, you should see an arrow pointing in the direction of where the data is going. An arrow may originate from a Source Resource to a Function or Destination Resource. Or from a Function to a Destination Resource. This will show you where your data is going directionally. Please note, we do not yet validate whether data is moving.

Viewing and Access

You can access the app visualization on the details page in the Meroxa Dashboard for the Turbine data app. This details page can be accessed directly through the dashboard or via a URL when using select commands in the Meroxa CLI.


Log in to your Meroxa account. Once authenticated, you should land on the Applications tab. This will list all Turbine data apps deployed to your account along with their state. Click on the application name of choice to view the details page. This is where your app visualization may be accessed.


Within the Turbine data app local project file, you may use meroxa app describe in the Meroxa CLI will output details about your Turbine data app. Provided with details about the Turbine data app subcomponents that exist, there will be a URL that can be used to access the visualization in the Meroxa Dashboard.

If you are working outside of the Turbine data app local project file, you can use meroxa app describe appname.

Using meroxa app list will display a table of all Turbine data apps deployed to your Meroxa account. This will include a direct URL to the Applications list page in the Meroxa Dashboard.

$ meroxa app list
