data-upload-java-cli

You can upload CSV data to Domo as a fallback by using the Java CLI to derive a schema from the file, create the dataset, and perform chunked data uploads when the JSON connector is unavailable or unsuitable.

Schema derivation for CSV ingestion reads your local CSV file headers and data types to automatically generate the schema definition required to create the corresponding Domo dataset before uploading.

Yes, you need Java and the domoutil.jar CLI tool installed in your local environment to execute the schema derivation, dataset creation, and chunked CSV upload workflow.

For large CSV data ingestion into Domo, the Java CLI performs chunked uploads with indexing to ensure reliable data transfer when the standard JSON connector is not suitable for the dataset size.

You should use the Java CLI instead of the Domo JSON connector when a REST or JSON API source is unavailable, unsuitable, or fails, providing a deterministic fallback pathway to move CSV data.

The primary limitation is that the Java CLI fallback requires a local CSV file and a local Java environment with domoutil.jar, making it less suitable for direct API streaming or remote automated pipelines.
