Noble Paul commented on SOLR-1229:
----------------------------------
Erik, the fix is not right
see this
{code}
key = map.get(dataImporter.getSchema().getUniqueKeyField().getName());
{code}
The name of the uniqueKey field in the scema and the one you have in the map
does not have to be same. DIH really gives you an option for it to be
different. The attribute 'pk' is only used for this purpose.
> deletedPkQuery feature does not work when pk and uniqueKey field do not have
> the same value

> 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.
