Subject [jira] [Commented] (OAK-8552) Minimize network calls required when creating a direct download URI
Date Fri, 23 Aug 2019 14:06:00 GMT

    [ https://issues.apache.org/jira/browse/OAK-8552?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16914292#comment-16914292

Thomas Mueller commented on OAK-8552:
-------------------------------------

* #getReference
** My vote would go to "introduce a new cleaner API Blob#isInlined (name can be changed)".
I might be more work, but I think the solution would be much clearer.
* #exists
** I think the exists method implies a network access (unless inlined).
** I'm afraid I don't currently understand why "remove the existence check" would "lead to
perceived performance drop"... I don't understand how "remove the existence check" would work
at all... I mean, it's reverting OAK-7998, right? If we revert OAK-7998 (which might be OK),
then I assume we need to solve the root problem of OAK-7998 in some other way.
