I did a quick search but couldn't find anything on this topic. We have a parent/child/grandchild relationship and our system has a dynamic number of parent mappings, but our child/grandchild mappings have a strict schema. This is because the data in the parent mapping is undefined and user submitted. So two questions: 1. Is OK to have thousands of parent mappings (which means thousands of child/grandchild mappings as well since a child can only have one parent) 2. Would a better approach be to have one massive parent mapping (potentially tens of thousands of fields)?
