Suggestion: Consider eBay/tsv-utils #1
Description
Hi Khosla,
Just came across your repo. It's a nice article, one that matches my own experiences.
In case you're not familiar with them, I'd like to suggest that you take a look at eBay's TSV Utilities. They were designed to address the data mining scenarios described in your post. The disclaimer of course is that I'm the author.
Even if the tools themselves don't fit your goals, you may find the performance benchmarks of interest, as they include several of the tools on your list.
