I am relatively new to Apache SOlr and have recently been working with DIH, specifically the XPathEntityProcessor. I need a way to periodically index new XML files, however, it appears the delta-import command is only supported by the sqlEntityProcessor [1].

I am working with an increasingly large dataset of XML files and was hoping solr could determine new files and index them…

A potential solution that came to mind is to possibly do a full-import from a staging area consisting of documents that have not been previously index, before moving the documents to their respective permanent locations.

  1. Is there a workaround to mimicking delte-import using XPathEntityProcessor?
  2. What sort of approaches do people using XPathEntityProcessor use to index newer documents?

    I’ve resorted to using the UpdateRequestHandler; it’s perfect for what I want to do.
