Comment: was deleted
(was: Hi [~varunthacker], I have met the same problem with you, after splitting
the rested document shard, it will lost index data, maybe after splitting, the
parent document has been send to shard1_0, the child document has been send to
shard1_1, so the child document has not find its parent, then it will be
invalid to be lost.
Have you found some method to avoid this problem? thanks!)
> Shard Split doesn't work on indexes that have nested documents

> Reporter: Varun Thacker
> Priority: Major
>
> 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
