Subject [jira] [Commented] (SOLR-3773) Hash based on the external String id rather than the indexed representation for distributed updates.
Date Thu, 30 Aug 2012 18:26:07 GMT

    [ https://issues.apache.org/jira/browse/SOLR-3773?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13445166#comment-13445166

Yonik Seeley commented on SOLR-3773:
------------------------------------

I'd go as far as to strongly recommend people use string as the type of their ID field.
Some of the ways I've thought about doing cloud in conjunction with nested documents and document
blocks involves encoding sub-children as 

The original idea around letting people specify their own uniqueKey field and fieldType was
that you could design a Solr schema that would be compatible with a random lucene index. 
I think that's rapidly becoming an outdated idea, and not worth the issues it causes.

> This makes some things easier - such as external systems doing the hashing themselves
(like CloudSolrServer).
> It will be back compat for String id types but not others. Sent an email to the list
a good time back seeing if this would bother anyone too much and got no replies.
