Solr - Achieve Delta-Import with the FileListEntityProcessor for PDF Files

[Karan Saini]

Solr version :: 6.6.1

I am using the solr to index the PDF files and it is working fine as
expected. Now i have a requirement to perform the option of delta-import on
the PDF file.
I am not able to locate the example of implementing the delta-import with
FileListEntityProcessor.

Please suggest.


*data-config.xml* file looks like this one.

<dataConfig>
  <dataSource type="BinFileDataSource"/>
  <document>
    <entity name="K1FileEntity" processor="FileListEntityProcessor"
dataSource="null"
            recursive = "true"
            baseDir="\\CLD02\RemoteDepot"
            fileName=".*pdf" rootEntity="false">

            <field column="file" name="id"/>
            <!--<field column="fileAbsolutePath" name="path" />
            <field column="fileSize" name="size" />-->
            <field column="fileLastModified" name="lastmodified" />

              <entity name="pdf" processor="TikaEntityProcessor"
onError="skip"
                      url="${K1FileEntity.fileAbsolutePath}" format="text">

                <field column="title" name="title" meta="true"/>
                <field column="dc:format" name="format" meta="true"/>
                <field column="text" name="text"/>

              </entity>
    </entity>
  </document>
</dataConfig>


Thanks,
Karan
