This allows updating only specific fields, which can help speed indexing processes in an environment where speed of index additions is critical to the application.

How does the prefix routing work in Solr?
Clients can use the (default) compositeId router’s “prefix routing” feature when indexing all documents to ensure that all child/descendent documents in a Block use the same id prefix as the Root level document. This will cause Solr’s default routing logic to automatically send child document updates to the correct shard.
