Subject [jira] [Commented] (OAK-4740) TarReader recovery skips generating the index and binary graphs
Date Thu, 01 Sep 2016 13:28:21 GMT

    [ https://issues.apache.org/jira/browse/OAK-4740?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15455378#comment-15455378

Alex Parvulescu commented on OAK-4740:
--------------------------------------

Ideally I would love to see the 2 methods of (re)generating a tar file being merged into a
single version (namely the {{sweep}} bits calling into the TarWriter and the {{generateTarFile}}
bits).

> 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.
