Error: Copy spanning locations and/or storage classes could not complete within 30 seconds.

Hello,

I'm getting the following error message on a client.cp() operation ...

Copy spanning locations and/or storage classes could not complete within 30 seconds. Please use the Rewrite method (https://cloud.google.com/storage/docs/json_api/v1/objects/rewrite) instead.

Is copying between buckets in different regions and/or storage classes supported?

Hi @bwalrond ,
While we never tried inter-region copying at Parquery since our data resides all in the same region, inter-region copying should work. Copying between buckets indeed has worked without problems so far.

The error message implies that copying takes too long (rather than it is not supported). Have you tried gsutil -- does it complain there as well?

[bwalrond]

gsutil doesn't complain. The copy_blob method won't work in these cases. According to the error message, the rewrite method is required.

@bwalrond I see. It would need a special switch, rewrite=True/False.

As I don't have access to Google cloud anymore (I changed my job), could you create two buckets and a big file and then grant me permissions so that I can develop against them and reproduce the error?
