fixes SAS-1443
requires opt-in (ramping up rate in plugin setting, defaults to 0). will
initially opt in on sandbox accounts, then trial accounts, then a
gradual roll out to avoid hammering the service.
when opted in (100%), asking for a redirect target for a file that's not
yet in inst-fs will first try to add it to Inst-FS by posting the
metadata only (a nominally quick transaction). Inst-FS can use this to
create a "foreign" reference to the existing object in canvas' s3 bucket
(which inst-fs should be given access to), at which point it can
immediately start serving the object.
opting in at a level above 0% but below 100% will have the chosen chance
of doing the above per-access.
if successful, Inst-FS returns the new instfs_uuid with which the
attachment is updated, then the redirect continues to inst-fs instead of
s3. if unsuccessful, opted-out, or skipped due to opt-in threshold, the
existing s3 object is redirected to as before.
test-plan:
(setup)
- have inst-fs integrated locally
- be using an s3 backing for non-instfs files
- give inst-fs access to that s3 backing
(testing)
- turn off the inst-fs plugin setting
- upload a file
- turn on the inst-fs plugin setting, but leave the migrating flag
unset
- access the previously uploaded file, should be served from s3
- turn on the migrating flag in the plugin setting
- access the previously uploaded file, should be served (or at least
attempted, if you haven't allowed inst-fs access to the canvas s3
bucket) from inst-fs
