Adi Kaminski commented on SOLR-12638:
-------------------------------------
So, in order to support integrity between parent-child document when parent or
child documents atomically updated, the schema should have the following 3
prerequisites ?
1. <field name="_root_" type="string" indexed="true" stored="*true*"
docValues="false" />
2. <fieldType name="_nest_path_" class="solr.NestPathField" />
3. <field name="_nest_path_" type="_nest_path_" />
Should _nest__path field have any additional attributed like stored=true,
docValues, others ?
Any other special prerequisites for the indexing syntax ? Should
_childDocuments used when indexing new parent-child documents or any other
syntax ?

> I have been toying with the thought of using this transformer in conjunction
> with NestedUpdateProcessor and AtomicUpdate to allow SOLR to completely
> re-index the entire nested structure. This is just a thought, I am still
> thinking about implementation details. Hopefully I will be able to post a
> more concrete proposal soon.
