Subject [jira] [Commented] (OAK-114) MicroKernel API: specify retention policy for old revisions
Date Wed, 04 Jul 2012 16:22:34 GMT

    [ https://issues.apache.org/jira/browse/OAK-114?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13406609#comment-13406609
] 

Stefan Guggisberg commented on OAK-114:
---------------------------------------

> Would it be possible to change "for at least 10 minutes" to "for at least 10 minutes
since last access"?

the 'extend lease model', apart from introducing complex state management requirements in
the microkernel,  would e.g. allow misbehaved clients to compromise the stability of the mk.
a client could force the mk to keep old revisions for ever and prevent vital gc cycles.

i therefore don't think that we should allow clients to (explicitly or implicitly) extend
the life span
of a specific revision.
