Chapter 4. The HBase Architecture
In the previous chapters, we learned the basic building blocks of HBase schema designing and applying the CRUD operations over the designed schema. In this chapter, we will look at HBase from its architectural view point on the following topics:
- Data storage
- Data replication
- Securing HBase
For most of the developers or users, the preceding topics are not of big interest, but for an administrator, it really makes sense to understand how underlying data is stored or replicated within HBase. Administrators are the people who deal with HBase, starting from its installation to cluster management (performance tuning, monitoring, failure, recovery, data security, and so on).
By the end of this chapter, we will also get an insight into the integration of HBase and Map Reduce. Let's start with data storage in HBase first.
