Radu Gheorghe commented on TIKA-694:

Thanks for following up, Tim! It makes perfect sense.

In my particular use-case, I don't mind the performance penalty of parsing the 
whole file to get metadata (though I think it's not needed in the very 
particular use-case of Emails). But I do run into trouble if the (potentially 
massive) body ends up in memory, because I can run out of heap. Using 0 bytes 
isn't too bad of a workaround, isn't it? :D

> I use TIKA to extract properties, and only, on Office files.
> The parser goes throw the document content and this is not necessary and slow 
> down the process.
> It would be nice to have choice to extract only properties or not.
> What I did was the following:
> Extension of AutoDetectParser to override the parse method.
> Then in the ParseContext instance, I put a flag with boolean true to say only 
> extract the properties.
> And for example, on office file, I extended OfficeParser class. During parse 
> method, I check the flag, and if equals to true, I removed all the extraction 
> from the content.
