I'll reply for Lance because I'm awake earlier <G>... To make your own DIH, you have to solve all the problems you'd have to solve to use a Java program connect to your datasource via JDBC, PLUS fit it into the DIH framework. Why do the extra work?
The other thing is that writing your own code gives you much greater control over, say, error handling, exception handling, continue-or-abort decisions, etc. DIH is a good tool, don't get me wrong, but I prefer more control in production situations. Plus, connecting to Solr via SolrJ AND connecting to your database takes about 20 lines of code, it's not very complex. You can have that done pretty quickly... But if you'd rather make your own DIH, it's up to you.
