[jira] [Commented] (SOLR-11191) Shard Split doesn't work on indexes
that have nested documents
[ https://issues.apache.org/jira/browse/SOLR-11191?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16439075#comment-16439075 ]
Peng Xing commented on SOLR-11191:
----------------------------------
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!

> 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
