I followed the steps mentioned @: http://wiki.apache.org/solr/DataImportHandler
I also tried other solution from stackoverflow however still it is not working.
Problem is: I have configured Delta-import handler still every time I run it; it indexes all records from DB. I have 30 records in DB. and every time I run delta import it is indexing all 30 records. I want only those which are changed/deleted should be indexed.
Any quick help/pointer/solution to this issue is appreciated.
Data-config.xml
<dataConfig>
<dataSource type="JdbcDataSource" name="ds-books" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost/test" user="root" password=""/>
<document name="books">
<entity name="books" pk="id" query="select * from books" deltaImportQuery="SELECT * FROM books WHERE id = '${dataimporter.delta.id}'" deltaQuery="SELECT id FROM books WHERE last_modified > '${dataimporter.last_index_time}'" >
<field column="id" name="id" indexed="true" stored="true"/>
<field column="NAME" name="name" />
<field column="PRICE" name="price" />
<field column="last_modified" name="last_modified" />
</entity>
</document>
</dataConfig>
Command that I am using to execute it is:
http://localhost:8983/solr/dataimport?command=delta-import
dataimport.properties file:
Fri May 10 17:13:18 IST 2013
last_index_time=2013-05-10 17\:13\:18
books.last_index_time=2013-05-10 17\:13\:18
dataimporter.last_index_time=2013-05-10 17\:11\:42

Changing following values in the data-config.xml has solved the problem
${dih.last_index_time} instead ${dataimporter.last_index_time}
${dih.delta.id} instead ${dataimporter.delta.id} .
I am using SOLR 4.0
