Jan Høydahl commented on SOLR-7632:
-----------------------------------

Following a [DISCUSS 
thread|https://lists.apache.org/thread/lbm6wb88gd1cfktgs6sfvw5xf73o8trd] on dev 
I'm working on a POC for this, in a hope to get rid Solr distribuion of the 
weight, complexity and inflexibility of bundled Tika.

I already have code that forwards the input stream to Tika-Server and receives 
and parses the JSON response of the parsed doc. Will post a PR eventually.

Once extraction module no longer depends on all the tika parsers, we can also 
move XLSXResponseWriter (depending on POI) out to a separate module.

> It's a pain to upgrade Tika's jars all the times when we release, and if Tika 
> fails it messes up the ExtractingRequestHandler (e.g., the document type 
> caused Tika to fail, etc). A more reliable way and also separated, and easier 
> to deploy version of the ExtractingRequestHandler would make a network call 
> to the Tika JAXRS server, and then call Tika on the Solr server side, get the 
> results and then index the information that way. I have a patch in the works 
> from the DARPA Memex project and I hope to post it soon.
