Subject [jira] [Commented] (SOLR-9320) A REPLACENODE command to decommission an existing node with another new node
Date Mon, 01 Aug 2016 18:32:20 GMT

    [ https://issues.apache.org/jira/browse/SOLR-9320?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15402587#comment-15402587

Nitin Sharma commented on SOLR-9320:
------------------------------------

I have a concern when this comes to scaling to 100s of collections. If you have 100+ collections,
this command will eventually timeout (> 3 mins) and this does this in serial. The patch
i sent (has multi threading capability), I ran with 500 collections and it finished around
4+ mins. Can you share the numbers with collections of that scale?
