As open source, big data tools enter the early stages of maturation, data engineers and data scientists will have many opportunities to use them to “work on stuff that matters”. Along those lines, computational biology and medicine are areas where skilled data professionals are already beginning to make an impact. I recently came across a compelling open source project from UC Berkeley’s AMPLab: ADAM is a processing engine and set of formats for genomics data.

Second-generation sequencing machines produce more detailed and thus much larger files for analysis (250+ GB file for each person). Existing data formats and tools are optimized for single-server processing and do not easily scale out. ADAM uses distributed computing tools and techniques to speedup key stages of the variant processing pipeline (including sorting and deduping):
