Transactional processing focuses on accessing and updating individual records. Analytical processing works on data in bulk and deals more with summaries across the dataset, trends and insights. The difference in requirements and the kind of data they work on, lead to differences between Hive and traditional databases.
This course, Getting Started with Hive for Relational Database Developers, teaches you about several gotchas involved while using familiar SQL constructs in Hive. You’ll learn about loading and parsing data from files, views, subqueries, and some cool built-in functionality such as table generating functions. The course also demonstrates the constraints imposed by Hive architecture choices such as schema on read, denormalized storage in HDFS, and high latency of operations. This serves as a guide for user choices during storage and querying. By the end of this course, you’ll feel confident in using Hive for your own relational database uses.
