> The split shard command doesn't split a shard correctly when the index has parent-child documents.
> The way split shard works is it goes through all documents id's in that shard and then decides which sub-shard would it belong in . It is not aware of the parent child relationship during this process
> So the parent-child documents could be orphaned and end up in different shard
> Secondly, even with the routing of parent and child documents were the same split shards needs to re-index them as a block
