[jira] Commented: (SOLR-1229) deletedPkQuery feature does not work when pk and uniqueKey field do not have the same value

["Erik Hatcher (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-1229?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12721264#action_12721264 ] 

Erik Hatcher commented on SOLR-1229:
------------------------------------

Maybe the pk field returned from deletedPkQuery should be run through the transformation process on the uniqueKey (id in this case) field to get the actual value??

>          Issue Type: Bug
>          Components: contrib - DataImportHandler
>    Affects Versions: 1.4

> Problem doing a delta-import such that records marked as "deleted" in the database are removed from Solr using deletedPkQuery.
> Here's a config I'm using against a mocked test database:
> <dataConfig>
>  <dataSource driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost/db"/>
>  <document name="tests">
>    <entity name="test"
>            pk="board_id"
>            transformer="TemplateTransformer"
>            deletedPkQuery="select board_id from boards where deleted = 'Y'"
>            query="select * from boards where deleted = 'N'"
>            deltaImportQuery="select * from boards where deleted = 'N'"
>            deltaQuery="select * from boards where deleted = 'N'"
>            preImportDeleteQuery="datasource:board">
>      <field column="id" template="board-${test.board_id}"/>
>      <field column="datasource" template="board"/>
>      <field column="title" />
>    </entity>
>  </document>
> </dataConfig>
> Note that the uniqueKey in Solr is the "id" field.  And its value is a template board-<PK>.
> I noticed the javadoc comments in DocBuilder#collectDelta it says "Note: In our definition, unique key of Solr document is the primary key of the top level entity".  This of course isn't really an appropriate assumption.
