[jira] [Comment Edited] (SOLR-5211) updating parent as childless
makes old children orphans
[ https://issues.apache.org/jira/browse/SOLR-5211?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15038352#comment-15038352 ]

-----------------------------------------------------------------
I want to address this. Thus, we have to assign identifier spans across whole block. However it makes <uniqueKey> semantics odd. Even if you send a single document, it _moves_ {{uniqueKey}} field value into {{\_root_}} field (as-is). Otherwise, we can propagate {{uniqueKey}} to whole block, but it would seem contradictionary.
Which way would you like?

> Project: Solr

> if I have parent with children in the index, I can send update omitting children. as a result old children become orphaned.
> I suppose separate \_root_ fields makes much trouble. I propose to extend notion of uniqueKey, and let it spans across blocks that makes updates unambiguous.
> WDYT? Do you like to see a test proves this issue?
