[jira] [Commented] (SOLR-5003) Add option to add rowid/line number to CSV Update Handler

["Yonik Seeley (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-5003?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13700923#comment-13700923 ] 

Yonik Seeley commented on SOLR-5003:
------------------------------------

{code}
+    //validate our row id
+    if (rowId != null && rowId.equals("") == false){
+      SchemaField sf = schema.getFieldOrNull(rowId);
+      if(sf == null)
+        throw new SolrException( SolrException.ErrorCode.BAD_REQUEST,"Invalid field name for rowId:'"+ rowId +"'");
+    }
{code}

In general, we should let downstream handle this type of stuff so things like schemaless will work.

> In some cases of exporting from a DB to CSV, the only "unique id" you have is the rowid.  This issue is to add an optional (off by default) rowid field to the document which simply contains the line number of the row.
