+ summary: Refreshes pre-signed URLs for files from a completed scan
planning result
+ description: >
+ Refreshes pre-signed URLs for a set of files that were returned as
part of a
+ previous server-side scan planning result, identified by its plan-id.
+
+
+ This endpoint is intended for lightweight, proactive renewal of
expiring URLs
+ (for example by a background caching daemon) and does not re-evaluate
the
+ table's manifests or any pushed-down filters. It is only available
when the
+ pre-signed-urls access delegation mechanism has been negotiated with
the
+ planTableScan endpoint via the X-Iceberg-Access-Delegation header.
Review Comment:
It seems like we're looking at this through a lens of pre-signing for
scan/plan, but if we decide to support this it should be generic for any access
method.
