	// 1) the story starts with more than 500 mil. compressed XML files stored in S3 (various sizes: 10KB - 200MB)
	// 2) the "small" files are grouped, decompressed, cleaned and stored as Parquet files
	// 3) the next piece of code converts the blob column to a column with a complex schema (more or less equivalent with the XML structure)
	// 4) the result can be persisted and afterwards queried in an efficient way

microKanren In Scala

	/**
	* An implementation of microKanren (and probably most of miniKanren), with
	* a few extras. Currently, it supports:
	*
	* - The essential core of microKanren: Unify, Fresh, Disjunction, Conjunction
	* - Standard terms: Variables, Atoms, TermCons, EmptyTerm.
	* - An implicit conversion from type T to Atom[T]. This makes writing programs
	* much easier.
	* - A decent reifier, which converts terms to strings.
