How can I delete an entire entity by specifying the type? #4311

Orion centex broker can add and update, but I think there is a need to delete naturally, but it is nonsense if there is none

Not sure of understanding want you mean... Do you mean that Orion should implement and API request to delete all entities of a given type?

(By the moment I'm going to remove the "bug" label as this doesn't seem to be a bug but a feature request)

sorry . actually it's not a bug but a feature request . i mean how can i delete entire entity of a given type. and other entity of type are not be deleted. for example There is a need to delete more than a thousand record of entity， now we can only delete entity by id. we have to foreach more then 1000 times to delete the entity。too inefficient。

I understand your "feature request" will be solved by https://github.com/telefonicaid/fiware-orion/issues/2389 (using idPattern: .* with a given type). Thus, I'd suggest to close this issue.

Btw, note #2389 has been labeled with "help wanted" so everybody is welcome to contribute with a solution for it in the form of pull request :)

On the meanwhile, this script could helpfull: https://github.com/telefonicaid/fiware-orion/blob/master/scripts/utils/delete_attribute_by_query.py. You can use a filter like this:

filter = '&type=<the type you want to delete>'

The script is old and it has not been migrated to work with Python 3 (it works with Python 2.7) but it would be easy to fix. In that case, if would be great if you could please contribute with the Python 3 version to the repository.
