Subject [jira] Updated: (SOLR-1229) deletedPkQuery feature does not work when pk and uniqueKey field do not have the same value
Date Wed, 01 Jul 2009 06:42:47 GMT

     [ https://issues.apache.org/jira/browse/SOLR-1229?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Noble Paul updated SOLR-1229:
-----------------------------

    Attachment: SOLR-1229.patch

Erik, the new fix

This eliminates the need for 'pk' most of the cases.  It tries to identify the corresponding
column mapping for the solr uniqueKey.  But the user can override this by specifying the pk
attribute if the guess is not going to be correct

> 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:
> {code:xml}
> <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>
> {code}
> 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.
