[jira] [Commented] (BOOKKEEPER-246) Recording of underreplication of ledger entries

    [ https://issues.apache.org/jira/browse/BOOKKEEPER-246?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13406423#comment-13406423 ] 

Ivan Kelly commented on BOOKKEEPER-246:
---------------------------------------

Also, this patch applies on top of (trunk+BOOKKEEPER-317). It does *not* require BOOKKEEPER-2. Which ever of BOOKKEEPER-2 and this goes in first, the other will have to resolve a conflict on the protobuf file.

> This JIRA is to decide how to record that entries in a ledger are underreplicated. 
> I think there is a common understanding (correct me if im wrong), that rereplication can be broken into two logically distinct phases. A) Detection of entry underreplication & B) Rereplication. 
> This subtask is to handle the interaction between these two stages. Stage B needs to know what to rereplicate; how should Stage A inform it?
