Batch deployment input details for Decision optimization models

Follow these rules when specifying input details for batch deployments of Decision optimization models.

Data type summary table:

Data Sources:

Input/output inline data:

• Inline input data is converted to CSV files and used by engine.
• CSV output data is converted to output inline data.
• Base64-encoded raw data is supported as input and output.

Input/output data references:

• Tabular data is loaded from CSV, XLS, XLSX, JSON files or database datasources supported by the WDP connection Library, converted to CSV files, and used by engine.
• CSV output data is converted to tabular data and saved to CSV, XLS, XLSX, JSON files or database datasources supported by the WDP connection Library.
• Raw data can be loaded and saved from/to any file datasources supported by the WDP connection Library.
• No support for ZIP files.
• The environment variables parameter of deployment jobs is not applicable.

If you are specifying input/output data references programmatically:

• Data source reference type depends on the asset type. Refer to the Data source reference types section in Adding data assets to a deployment space.
• For S3 or Db2, connection details must be specified in input_data_references.connection parameter, in the deployment job’s payload.
• For S3 or Db2, location details such as table name, bucket name or path must be specified in input_data_references.location.path parameter, in the deployment job’s payload.
• For data_asset, a managed asset can be updated or created. In case of creation you can set the name and description for the created asset.

• You can use a pattern in id or connection properties. For example:

  • To collect all output CSV as inline data:

    "output_data": [ { "id":".*\\.csv"}]
    

  • To collect job output in a particular S3 folder:

    "output_data_references": [ {"id":".*", "type": "s3", "connection": {...}, "location": { "bucket": "do-wml", "path": "${job_id}/${attachment_name}" }}]
    

Note Support for s3 and db2 values for scoring.input_data_references.type and scoring.output_data_references.type is deprecated and will be removed in the future. Use connection_asset or data_asset instead. See the documentation for the Watson Machine Learning REST API or Watson Machine Learning Python client library for details and examples.
