Re-architect relational applications to NoSQL, integrate relational database
management systems with the Hadoop
ecosystem, and transform and migrate relational data to and from Hadoop
components. This book covers the best-practice design
approaches to re-architecting your relational applications and transforming your relational data for usage with the Hadoop
ecosystem while considering concurrency, security, denormalization, and optimal performance.
Winner of IBM's 2012 Gerstner Award for his implementation of big data and data warehouse initiatives and author of Practical Hadoop
Security, author Bhushan Lakhe walks you through the entire transition process. First, he lays out the criteria for deciding what blend of re-architecting, migration, and integration between RDBMS and HDFS best meets your transition objectives. Then he demonstrates how to design
your transition model.
Hadoop/NoSQL solutions do not offer by default certain relational technology features such as role-based access
control, locking for concurrent updates, and various tools for measuring and enhancing performance. Practical Hadoop
Migration shows how to use open-source tools to emulate such relational functionalities in Hadoop
