[jira] [Comment Edited] (SOLR-3755) shard splitting
[ https://issues.apache.org/jira/browse/SOLR-3755?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13601143#comment-13601143 ]

------------------------------------------------------------
Anshum caught me up in chat - I am actually the one that is confused - because slice state stuff has already been committed. I thought I was looking at pre shard splitting trunk code.
The real problem here is how the slice state is being handled in relation to clusterstate.json updates - you can lose inactive slices from the clusterstate which will cause havoc.

> We can currently easily add replicas to handle increases in query volume, but we should also add a way to add additional shards dynamically by splitting existing shards.
