[jira] [Resolved] (SOLR-15468) Regression: Adding _root_ schema
field to existing index causes atomic update failures
[ https://issues.apache.org/jira/browse/SOLR-15468?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
David Smiley resolved SOLR-15468.
---------------------------------
Resolution: Not A Problem
My thoughts exactly! Yes, just a strong warning in the ref guide.
I'm glad I added the safety check some months ago :-)
> Regression: Adding _root_ schema field to existing index causes atomic update failures

> Key: SOLR-15468
> URL: https://issues.apache.org/jira/browse/SOLR-15468
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: update
> Affects Versions: 8.8
> Reporter: Andreas Hubold
> Priority: Major
> Labels: regression
>
> In previous Solr releases (8.6.3) it was possible to add the \_root\_ field to the schema of an existing index, e.g to add functionality relying on child documents without reindexing all documents.
> This does not work anymore with Solr 8.8.2, because SOLR-14923 added a check in RealTimeGetComponent#getInputDocument that the root field contains the expected value. IIUC, the check does not only fail for wrong values, but also if the root field does not contain any value yet, as it's the case for documents that were added before the field was added to the schema.
> The check causes atomic/partial updates to fail:
> {noformat}
> Caused by: org.apache.solr.common.SolrException: Attempted an
> atomic/partial update to a child doc without indicating the _root_ somehow.
