About Professional Data Engineering
Big Data solutions are incredibly complex. They usually entail the correct application of five to ten or more complicated technologies, all working together. That increase in complexity is the reason why Big Data is such a different animal. There is an order of magnitude increase in the complexity over small data.
This course is only intended for teams and companies facing real big data problems. We focus on practical use cases and real-world applications for teams and companies. The course doesn’t just show the technologies; we show how they’re used in data pipelines and how professional Data Engineers use them.
Duration: Online – Two weeks of concerted effort/Eight weeks of less effort

An understanding of how Spark works and how each phase works.
- What are Java 8 Lambdas and how they make your Spark code humanly readable?
- The basics of coding a Spark job with Java to build your Big Data foundation.
- The various API methods in Spark and what they do.
- How SQL can be used with a Spark job and when that vastly improves your productivity and code.
- How to create Java code that runs as a function during a Spark SQL command to use existing Java code or do use case-specific queries.

- What the advanced features of the MapReduce API that only the true experts know.
- How Apache Crunch gives you a very different API from MapReduce and gives you a more Java-centric API.
- How to use Apache Crunch to do the things not humanly possible in MapReduce like joining datasets and performing secondary sorts.
- The simple and advanced SQL-like commands available in Hive.
- How to extend Hive commands with custom non-Java code to do company or use case-specific queries.
- How to move data out of and into relational databases like MySQL and Oracle from Hadoop/Spark using Apache Sqoop.
- How to move files and network data from many different computers to Hadoop using Apache Flume.
- What is Hue and how it aids in creating browser-based data products?
- How Apache Oozie makes it possible to create repeatable workflows that enterprises need.
- How all of these technologies come together as a solution for ETL, clickstream, and sessionization use cases.
