I am trying to import a azure db backup .I want to use the chunk-size parameter. I am using

  az sql db import --resource-group <resource_group_name> --server <server_name> --name <database_name> --storage-key <storage_account_key> --storage-key-type StorageAccessKey --storage-uri <storage_account_uri> --administrator-login <admin_username> --administrator-login-password <admin_password> --authentication-type SQL --chunk-size-mb 100

But it says “z : ERROR: unrecognized arguments: –chunk-size-mb 100”.
How can i import in small amounts to combat memry issues ?
