Get request status

[valpesendorfer]

Hello,

before migrating to the new CDS platform, it was possible to check a request's status through querying https://cds.climate.copernicus.eu/api/tasks/<id>. After migration, this URL route returns a 404 response.

Is there any possibility to check a requests status programmatically with the new CDS?

Thanks!

(This is related to the issue ecmwf/cdsapi#122 and the corresponding ECMWF forum post)

Hi there,

This is supported in cads-api-client as follows:

from cads_api_client import ApiClient

client = ApiClient()
remote = client.get_remote(REQUEST_UID)
remote.status

Please note that at the moment cads-api-client is not considered stable, and the official package recommended by ECMWF is cdsapi.

thanks @malmans2 for the quick response.

Is cads-api-client going to become stable and the eventual replacement for interacting with CDS? As far as I understand, the newer cdsapi is "wrapping" the cads-api-client LegacyApiClient - is there any chance the status could be surfaced through there to the cdsapi?

Thanks again

Unfortunately, I'm not the right person to address this question.

You are correct that there is a LegacyApiClient used to ensure backward compatibility with the cdsapi.Client methods. The reason you're unable to retrieve a job using the request ID is because you are manually instantiating the Result object.

If you’d like to continue using cdsapi exclusively, you can do the following:

cdsapi_client = cdsapi.Client(...)
remote = cdsapi_client.client.get_remote(REQUEST_UID)

where cdsapi_client.client is the cads_api_client.ApiClient used under the hood. However, please note that also this snippet is not guaranteed to be stable.
