Easy Analysis of HDF5 Data

There is a data format called HDF5 (Hierarchical Data Format) which is used extensively in scientific research. HDF5 is an interesting format in that it is like a file system within a file, and is extremely performant. However, the HDF5 format can be quite difficult to actually access the data that is encoded in HDF5 format. But, as the title suggests, this post will walk you through how to easily access and query HDF5 datasets using my favorite tool: Apache Drill.

As of version 1.18 Drill will natively support reading HDF5 files.
