I have used the following and it works very fast in DIH solr-5.0
<dataSource name="URL" type="FileDataSource" />
<document name="map">
<entity
name="sites"
processor="org.apache.solr.handler.dataimport.LineEntityProcessor"
dataSource="URL"
url="/opt/solr/solrfiles/descriptions.csv"
rootEntity="false"
separator=","
transformer="RegexTransformer"
>
<field column="rawLine" regex="([^,]+),([^,]+),(.*)$"
groupNames="id,mydata," />
</entity>
<document>
You can try this for getting groupNames from regex.
