This document discusses a project between Pentaho and Verizon to leverage big data analytics. Verizon generates vast amounts of call detail record (CDR) data from mobile networks that is currently stored in a data warehouse for 2 years and then archived to tape. Pentaho's platform will help optimize the data warehouse by using Hadoop to store all CDR data history. This will free up data warehouse capacity for high value data and allow analysis of the full 10 years of CDR data. Pentaho tools will ingest raw CDR data into Hadoop, execute MapReduce jobs to enrich the data, load results into Hive, and enable analyzing the data to understand calling patterns by geography over time.
