Subject [jira] [Commented] (SOLR-3246) UpdateRequestProcessor to extract Solr XML from rich documents
Date Wed, 14 Mar 2012 23:20:40 GMT


Jan Høydahl commented on SOLR-3246:

We wrote a data dumper in a project as a patched ExtractingUpdateRequestHandler. It writes
a CSV format (including Base64 encoded binary input) to one file. We were thinking about rewriting
it as an UpdateProcessor, which will then work much like yours. The benefit with CSV format
is that it is much more compact. Also, a file system may kneal with too many files in a folder.

> This would be an update request handler to save a file with the xml that represents the
document in an external directory. The original
> idea behind this was to add it to the processing chain of the ExtractingRequestHandler
to store an already parsed version of the docs. This storage of pre-parsed documents will
make the re indexing of the entire index faster (avoiding the Tika phase, and just sending
the xml to the standard update processor).
> As a side effect, extracting the xml can make debugging of rich docs easier.
