Joshua Hawkinson created LIBCLOUD-986:
-----------------------------------------
Summary: List / Iterate container with prefix for Azure Blob
service (in addition to the other drivers)
Key: LIBCLOUD-986
URL: https://issues.apache.org/jira/browse/LIBCLOUD-986
Project: Libcloud
Issue Type: Improvement
Components: Storage
Reporter: Joshua Hawkinson
While testing out the libcloud storage abstraction I've come across a curious
omission in driver support. It seems that for many drivers there is additional
support for the \{list_container_objects()} and
{iterate_container_objects to support a prefix. This functionality is not
present in the Azure driver for some reason. I've gone and checked the
list_blobs API and ti also supports this functionality as seen here:
[https://docs.microsoft.com/en-us/rest/api/storageservices/list-blobs] I've
attempted a quick and dirty patch that seems to work as well.
