Run a data flow

post

/api/20210901/catalog/dataflows/{dataflowId}/actions/run

Run an existing data flow with a given id. If the request body includes parameters, the data flow runs with the given parameters. If no request body is provided, the data flow runs as-is. Returns an oa-work-request-id so you can monitor progress.

Examples

These examples show you how to run a data flow with a given dataflowID with or without parameters.

• Example 1 - Run a data flow without parameters
• Example 2 - Run a data flow with parameters
• Example 3 - Run a data flow with parameters defined in a JSON file (multiple dataset targets)
• Example 4 - Run a data flow with parameters in a JSON file (Essbase cube target)

When you run a data flow, you can specify several, optional parameters in the request body. Parameters allow you to specify inputs and outputs for the data flow at runtime.

• parameterName - Identifier for a source dataset or a target dataset to be replaced.
• datasetName - Name of the dataset. The dataset must exist and you must have permission to use the dataset in the data flow.
• type - Type of data flow parameter. Valid values: source, target, cube
• appParameterName - Identifier for the target Essbase application.
• appName - Name of the target Essbase application.
• cubeParameterName - Identifier for the target Essbase cube.
• cubeName - Name of the target Essbase cube.

Example 1 Run a data flow without parameters

In this example, you run a data flow job with a given dataflowID. The object ID of the data flow is 'adminuser'.'mySalesDataFlow2024' which has the Base64URL-safe encoded dataflowID value: J2FkbWludXNlcicuJ215U2FsZXNEYXRhRmxvdzIwMjQn

cURL Example:

First, obtain the object ID of the data flow you want to run and Base64URL-safe encode this value to determine the dataflowID. You can obtain the Object ID value from the Inspect dialog for data flow in Oracle Analytics Cloud.

Run the cURL command with the required dataflowID:

curl -i \
     --header 'Authorization: Bearer <token>' \
     --header 'Content-Type: application/json' \
     --request POST 'https://<hostname>/api/20210901/catalog/dataflows/J2FkbWludXNlcicuJ215U2FsZXNEYXRhRmxvdzIwMjQn/actions/run' \

Example 2 Run a data flow with parameters

In this example, you run a data flow with source and target parameters. The object ID of the data flow is 'adminuser'.'myOrdersDataFlow2024' which has the Base64URL-safe encoded dataflowID value: J2FkbWludXNlcicuJ215T3JkZXJzRGF0YUZsb3cyMDI0Jw

• Source parameters - Identify one or more dataset sources for the data flow. In this example, the input to the data flow is a single dataset, SalesDataset.
• Target parameters - Identify one or more datasets output from the data flow. In this example, the output from the data flow is a single dataset, mySalesDataset2024.

cURL Example:

First, obtain the object ID of the data flow you want to run and Base64URL-safe encode this value to determine the dataflowID. You can obtain the Object ID value from the Inspect dialog for data flow in Oracle Analytics Cloud.

Run the cURL command with the required dataflowID:

curl -i \
     --header 'Authorization: Bearer <token>' \
     --header 'Content-Type: application/json' \
     --request POST 'https://<hostname>/api/20210901/catalog/dataflows/J2FkbWludXNlcicuJ215T3JkZXJzRGF0YUZsb3cyMDI0Jw/actions/run' \

Example 3 Run a data flow with parameters defined in a JSON file (multiple dataset targets)

In this example, you run a data flow with multiple source and target parameters defined in a JSON file (mydataflowparameters.json). The object ID of the data flow is 'adminuser'.'myProductSalesDataFlow2024' which has the Base64URL-safe encoded dataflowID value: J2FkbWludXNlcicuJ215UHJvZHVjdFNhbGVzRGF0YUZsb3cyMDI0Jw

• Source parameters - Identify one or more dataset sources for the data flow. In this example, there are two inputs to the data flow: Product1Dataset and Product2Dataset.
• Target parameters - Identify one or more datasets output from the data flow. In this example, there are two outputs from the data flow: myProduct1Dataset2024 and myProduct2Dataset2024.

cURL Example:

First, obtain the object ID of the data flow you want to run and Base64URL-safe encode this value to determine the dataflowID. You can obtain the Object ID value from the Inspect dialog for data flow in Oracle Analytics Cloud.

Next, create a JSON file that contains the parameters required to run the data flow. For example, create a JSON file called mydataflowparameters.json with a payload that looks like this.

{"parameters":       
      [
            {
               "parameterName":"Source Input - Product1",
               "datasetName":"Product1Dataset",
               "type":"source"
             },            
             {
               "parameterName": "Source Input - Product2",
               "datasetName": "Product2Dataset",  
               "type": "source"
            },

               "datasetName": "myProduct1Dataset2024",
               "type":"target"
            },
            {
               "parameterName": "Target Output - newDatasetProduct2",
               "datasetName": "myProduct2Dataset2024",
               "type": "target"       
            }
       ]
}

Run the cURL command with the required dataflowID:

curl -i \
     --header 'Authorization: Bearer <token>' \
     --header 'Content-Type: application/json' \
     --request POST 'https://<hostname>/api/20210901/catalog/dataflows/J2FkbWludXNlcicuJ215UHJvZHVjdFNhbGVzRGF0YUZsb3cyMDI0Jw/actions/run' \
