There is a command group 'az_dt_job_import'. This group of commands could 'manage and configure jobs for importing model  twin and relationships data to a digital twin instance'. The group of commands has global parameter '--debug' which means 'Increase logging verbosity to show all debug logs.'. The group of commands has global parameter '--help -h' which means 'Show this help message and exit.'. The group of commands has global parameter '--only-show-errors' which means 'Only show errors, suppressing warnings.'. The group of commands has global parameter '--output -o' which means 'Output format.'. The group of commands has global parameter '--query' which means 'JMESPath query string. See <a href="http://jmespath.org/">http://jmespath.org/</a> for more information and examples.'. The group of commands has global parameter '--subscription' which means 'Name or ID of subscription. You can configure the default subscription using `az account set -s NAME_OR_ID`.'. The group of commands has global parameter '--verbose' which means 'Increase logging verbosity. Use --debug for full debug logs.'. This group contains a child command 'az_dt_job_import_create'.The syntax is: az dt job import create --data-file
                        --dt-name
                        --ibc
                        --input-storage-account
                        [--job-id]
                        [--obc]
                        [--of]
                        [--osa]
                        [--resource-group]. The 1th example of the child command would be to use it to 'creates a job for importing data file stored in an azure storage container  import job s output file is created in the input file s blob container', the syntax is: az dt job import create -n {instance_or_hostname} --data-file {data_file_name} --input-blob-container {input_blob_container_name} --input-storage-account {input_storage_account_name} --output-file {output_file_name}. The 2th example of the child command would be to use it to 'creates a job for importing data file stored in an azure storage container  import job s output file is created in user defined storage account and blob container', the syntax is: az dt job import create -n {instance_or_hostname} --data-file {data_file_name} --input-blob-container {input_blob_container_name} --input-storage-account {input_storage_account_name} --output-file {output_file_name} --output-blob-container {output_blob_container_name} --output-storage-account {output_storage_account_name}. The parameter '--data-file --df' is required. It is used to name of data file input to the bulk import job. the file must be in 'ndjson' format. sample input data file: https://github.com/azure/azure-iot-cli-extension/tree/dev/docs/samples/adt-bulk-import-data-sample.ndjson.. The parameter '--dt-name --dtn -n' is required. It is used to digital twins instance name or hostname. if an instance name is provided, the user subscription is first queried for the target instance to retrieve the hostname. if a hostname is provided, the subscription query is skipped and the provided value is used for subsequent interaction.. The parameter '--ibc --input-blob-container' is required. It is used to name of azure storage blob container which contains the bulk import data file.. The parameter '--input-storage-account --isa' is required. It is used to name of azure storage account containing blob container which stores the bulk import data file.. The parameter '--job-id -j' is optional. id of job. a system generated id is assigned when this parameter is ommitted during job creation.. The parameter '--obc --output-blob-container' is optional. name of azure storage blob container where the bulk import job's output file will be created. if not provided, will use the input blob container.. The parameter '--of --output-file' is optional. name of the bulk import job's output file. this file will contain logs as well as error information. the file gets created automatically once the job finishes. the file gets overwritten if it already exists. if not provided the output file is created with the name: <job_id>_output.txt.. The parameter '--osa --output-storage-account' is optional. name of azure storage account containing blob container where bulk import job's output file will be created. if not provided, will use the input storage account.. The parameter '--resource-group -g' is optional. digital twins instance resource group. you can configure the default group using `az configure --defaults group=<name>`..
