# I have added the property
{noformat}fs.azure.saskey.usecontainersaskeyforallaccess{noformat} declaration
to core-default.xml.
# The shared sasKey generator makes a request to a service called "delegation
token service" to fetch a sas-key. This is an expensive call. This code change
makes available another option, where the user contacts Delegation token
service only once, to fetch the container sas-key. All other blob-specific keys
re-use the container sas-key and don't make that call to DTS. This provides a
performance boost.
# I tested this manually.

> This JIRA tracks adding support for using container saskey for all storage
> access.
> Instead of using saskeys that are specific to each blob, it is possible to
> re-use the container saskey for all blob accesses.
> This provides a performance improvement over using blob-specific saskeys
