Subject [jira] [Commented] (SOLR-2880) Investigate adding an overseer that can assign shards, later do re-balancing, etc
Date Wed, 07 Dec 2011 15:30:40 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2880?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13164457#comment-13164457
] 

Yonik Seeley commented on SOLR-2880:
------------------------------------

Some random comments so far... Naming:
 - numShards vs num_shards... we should try to make system properties consistent with the
names that actually appear in ZK
 - _core, _collection? why the underscores? 

I'm not sure num_shards belongs as a configuration item anywhere (in solr.xml or as a collection
property in ZK). The number of shards a collection has is always just the number you see in
ZK under the collection. This will make it easier for people with custom sharding to just
add another shard. Whoever is creating the initial layout should thus create all of the shards
at once.
