--------------------------------
A draft PR covering the proposed feature is at

proposal in this PR.
> Allow direct download client to specify a shorter signed URI TTL

> Key: OAK-9710
> URL: https://issues.apache.org/jira/browse/OAK-9710
> Project: Jackrabbit Oak
> Issue Type: Story
> Components: blob-cloud, blob-cloud-azure, blob-plugins
> Affects Versions: 1.42.0
> Reporter: Matt Ryan
> Assignee: Matt Ryan
> Priority: Major
>
> When you request a direct download URI from cloud blob storage, the TTL that
> is specified for the URI is set to a default value that is specified in
> configuration.
> The proposal here is to consider extending the capabilities of requesting a
> direct download URI such that a client can specify their own TTL, *so long
> as* that TTL does not exceed a maximum value specified in the configuration.
> In other words - suppose the default configured TTL is 1800 (30 minutes) and
> the configured max TTL is 3600 (60 minutes). In this case:
> * A client that does not specify any other TTL value would get URIs that
> expire in 1800 seconds.
> * A client that chooses to specify a TTL value could provide any value
> greater than 0 but less than or equal to 3600 seconds.
> * Specifying a TTL value of over 3600 would be an error condition.
> * Specifying a TTL value of 0 would be an error condition.
> * Specifying a TTL value of less than 0 would be the same as the default
> value (-1), meaning to use the configured value (i.e. 1800 seconds).
> The maximum TTL value would be considered an optional configuration value.
> If not specified, the default configured TTL would be used (which is required
> to enable the direct download feature). If specified but lower than the
> default, the actual max would be the default value (i.e. {{{}max(default TTL,
> max TTL){}}}).
> What should happen if an error condition should occur? Typically in the
> direct download code an error results in the return of a {{null}} value for
> the URI, accompanied by a log message - so that'd be my proposal for this
> situation also.
