BigTable/HBase Architecture

Understand the distributed data store architecture of HBase, inspired by BigTable. Learn about its sparse multi-dimensional data model, region-based partitioning, HManager and region servers roles, and how Zookeeper supports cluster coordination and fault tolerance.

We'll cover the following...

BigTableF. Chang et al., “Bigtable: A Distributed Storage System for Structured Data,” in Proceedings of 7th {USENIX} Symposium on Operating Systems Design and Implementation (OSDI), 2006. is a distributed storage system initially developed in Google and was the inspiration for HBase, a distributed datastore that is part of the Apache Hadoop project.

Note that the architecture of these two systems is very similar to each other, so we will focus only on HBase, which is an open-source system.

HBase data model

HBase provides a sparse, multi-dimensional sorted map as a data model, as shown in the ...
