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.'.

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_cosmosdb_dts_copy'.The syntax is: az cosmosdb dts copy --account-name
                     --resource-group
                     [--dest-cassandra-table]
                     [--dest-mongo]
                     [--dest-sql-container]
                     [--job-name]
                     [--source-cassandra-table]
                     [--source-mongo]
                     [--source-sql-container]
                     [--worker-count]. The 1th example of the child command would be to use it to 'copy sql container', the syntax is: az cosmosdb dts copy -g "rg1" --job-name "j1" --account-name "db1" --source-sql-container database=db1 container=c1 --dest-sql-container database=db2 container=c2. The 2th example of the child command would be to use it to 'copy cassandra table', the syntax is: az cosmosdb dts copy -g "rg1" --job-name "j1" --account-name "db1" --source-cassandra-table keyspace=k1 table=t1 --dest-cassandra-table keyspace=k2 table=t2. The 3th example of the child command would be to use it to 'copy mongo collection', the syntax is: az cosmosdb dts copy -g "rg1" --job-name "j1" --account-name "db1" --source-mongo database=d1 collection=c1 --dest-mongo database=d2 collection=c2. The parameter '--account-name -a' is required. It is used to name of the cosmosdb database account.. The parameter '--resource-group -g' is required. It is used to name of resource group. you can configure the default group using `az configure --defaults group=<name>`.. The parameter '--dest-cassandra-table' is optional. destination cassandra table.. The parameter '--dest-mongo' is optional. destination mongo collection.. The parameter '--dest-sql-container' is optional. destination sql container.. The parameter '--job-name -n' is optional. name of the data transfer job. a random job name will be generated if not passed.. The parameter '--source-cassandra-table' is optional. source cassandra table.. The parameter '--source-mongo' is optional. source mongo collection.. The parameter '--source-sql-container' is optional. source sql container.. The parameter '--worker-count' is optional. worker count..
