Part 3 moves past toy example applications and gives you a taste of HBase in real applications. Chapter 7 is a deep-dive into OpenTSDB, an infrastructure-monitoring application designed for efficient storage and query of time-series data. In chapter 8, you get a glimpse at using HBase for geospatial data. You’ll learn how to adapt an HBase schema for multidimensional spatial data as you implement multiple spatial queries. When you finish this part of the book, you’ll be ready to architect your own distributed, fault-tolerant, HBase-backed data systems from the ground up.
