Subject [jira] [Commented] (OAK-4740) TarReader recovery skips generating the index and binary graphs
Date Thu, 15 Sep 2016 13:30:20 GMT

    [ https://issues.apache.org/jira/browse/OAK-4740?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15493322#comment-15493322

Michael Dürig commented on OAK-4740:
------------------------------------

Yes that would also help my understanding what this issue was about initially... is recovery
for the binary index completely broken or did we just break it for binaries with > 4k ids?
My fix applies to the latter only.

> As noticed from the tar recovery bits [0] the resulting tar file would lack the binary
reference graph and index graph. This has implications on the DSGC (not properly reporting
binary references would result in binaries being GC'ed) and GC operations.
