Question about Indexing Updated Documents

Hi Guys,

I have a data-import handler set up that indexes all of the documents from a few small tables.

What is the best way to update the index when a single one of those documents change.

Is it possible to use SQL or must I post json or xml to solr?

Thanks you,

Sas

If you are already using DIH, then you can use a 
deltaQuery to find "updated" documents and index only 
them.

Some people just parameterize their main DIH query and use request params 
to control which documents get indexed when doing a "full build"...
