Matt Ryan commented on OAK-8280:
--------------------------------
The proposed changes can be reviewed here:
https://github.com/apache/jackrabbit-oak/pull/162
This adds the ability for a client to specify to ignore the domain override
when generating direct access upload or download URIs. The use case (mentioned
as something needed before) is that sometimes a client may have enough
knowledge to know that certain requested URIs will result in faster throughput
if the domain override is not used. An example is a third-party VM running as
a service in the same cloud region as where the blob storage is, which based on
my testing (at least with Azure) gives many times faster access time if going
direct to storage using the default domain rather than using a CDN domain
(which would be faster for clients not within the Azure region). With this
change the client can request signed URIs that do not apply any domain
override, if one is configured.

> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: blob-cloud, blob-cloud-azure
> Reporter: Matt Ryan
> Priority: Major
>
> As we learned in OAK-7702, using signed CDN URIs usually offers improved
> throughput, but not always. Implementing this issue would mean that we
> extend the API to allow a client to indicate that they do not want the CDN
> URI, even if a CDN is configured, because the client somehow knows that the
> non-CDN URI will be better.
