There is a command group 'az_dt_data history_connection'. This group of commands could 'manage and configure data history connections'. 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_data history_connection_delete'.The syntax is: az dt data-history connection delete --cn
                                     --dt-name
                                     [--clean {false, true}]
                                     [--no-wait]
                                     [--resource-group]
                                     [--yes]. The 1th example of the child command would be to use it to 'delete a data history connection configured on an instance and block until the operation is complete', the syntax is: az dt data-history connection delete -n {instance_name} --cn {time_series_database_connection_name}. The 2th example of the child command would be to use it to 'delete a data history connection configured on an instance without confirmation or blocking', the syntax is: az dt data-history connection delete -n {instance_name} --cn {time_series_database_connection_name} -y --no-wait. The 3th example of the child command would be to use it to 'delete a data history connection configured on an instance and attempt to clean up artifacts that were created when the connection was created  if appropriate permissions are not in place  the attempt may fail  recorded data will not be deleted', the syntax is: az dt data-history connection delete -n {instance_name} --cn {time_series_database_connection_name} --clean. The parameter '--cn --conn-name' is required. It is used to name of data history connection.. The parameter '--dt-name --dtn -n' is required. It is used to digital twins instance name.. The parameter '--clean -c' is optional. specifies whether or not to attempt to clean up artifacts that were created in order to establish a connection to the time series database. this is a best-effort attempt that will fail if appropriate permissions are not in place. setting this to 'true' does not delete any recorded data.. The parameter '--no-wait' is optional. do not wait for the long-running operation to finish.. The parameter '--resource-group -g' is optional. digital twins instance resource group. you can configure the default group using `az configure --defaults group=<name>`.. The parameter '--yes -y' is optional. do not prompt for confirmation..
