DataImportHandler and Blobs

[Grant Ingersoll]

Am I understanding the DIH correctly in that it doesn't work with  
Blobs and or binary things?   I'm basing this off of  
JdbcDataSource.getARow() which seems to be the place that populates  
the Map that is then passed to the Transformer.

One of the things that I think might be interesting is, as I'm  
integrating Tika, the notion of a Transformer that takes a blob and  
feeds it to Tika for parsing.  In this way, people that store  
documents in databases (or download PDFs, etc.) can use the DIH to  
bring in more kinds of content.

Thoughts?
