Subject [jira] [Commented] (SOLR-3755) shard splitting
Date Fri, 05 Apr 2013 11:10:19 GMT

    [ https://issues.apache.org/jira/browse/SOLR-3755?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13623537#comment-13623537

Anshum Gupta commented on SOLR-3755:
------------------------------------

I've run into a few more issues while trying to improve the error handling/reporting.

1. Splitting an existing sub-shard gets stuck up. The new sub-sub shards stay in construction
state forever.
2. The replicas are generally always created on the same node. (Debugging/fixing that)

> 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.
