[jira] [Assigned] (SOLR-15064) Atomic/partial updates to nested
docs should not assume _route_ param is the root ID

Description:
In SOLR-14923, doing an atomic/partial update to a child doc requires indicating what the root doc ID is. Formerly Solr tried to figure this out automatically, but that had costly implications. SOLR-14923 adds a temporary hack that assumes that the \_route_ paramter *is* the root ID, if the \_root_ field is not on the doc. But that's not necessarily accurate, so it should be removed.
was:
Doing an atomic/partial update to a child doc requires that the update be routed to the proper shard despite the doc having an ID different than the root doc that it's associated with. Our solution for that was to use the {{_route_}} param to supply the root document ID. What we overlooked was the fact that implicit routers rely on that parameter to identify the shard by name. Consequently, these two features are incompatible.
I think we must insist that such updates include the {{_root_}} field in the document, and take care to exclude it when applying in-place updates (as its presence would disrupt the ability to do an in-place update). Furthermore, ensure that CloudSolrClient and Solr itself can route updates appropriately based on the {{_root_}} field.
Priority: Minor (was: Major)
Summary: Atomic/partial updates to nested docs should not assume _route_ param is the root ID (was: Atomic/partial updates to nested docs is incompatible with implicit doc router)
