Subject [jira] [Commented] (OAK-2498) Root record references provide too little context for parsing a segment
Date Thu, 15 Sep 2016 15:57:20 GMT

    [ https://issues.apache.org/jira/browse/OAK-2498?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15493751#comment-15493751

Michael Dürig commented on OAK-2498:
------------------------------------

For OAK-4740 we also need to be able to identify references to external binaries. More generally
I would suggest we specialise the VALUE type to the different types of values.

> According to the [documentation | http://jackrabbit.apache.org/oak/docs/nodestore/segmentmk.html]
the root record references in a segment header provide enough context for parsing all records
within this segment without any external information. 
> Turns out this is not true: if a root record reference turns e.g. to a list record. The
items in that list are record ids of unknown type. So even though those records might live
in the same segment, we can't parse them as we don't know their type.
