Course Description
This course teaches you how to write programs in Apache Storm to take streaming data from tools like Kafka and Twitter in real time, process in Storm and save to tables in Cassandra or files in Hadoop HDFS. You will be able to develop distributed stream processing applications that can process streaming data in parallel and handle failures. You will be able to implement data transformations like maps and filters in Apache Storm, implement stateful stream processing and exactly once processing. It covers some administrative aspects also like setting up an Apache Storm cluster, scheduling, monitoring and metrics reporting.
This is a hands on course, so you will be developing many Apache Storm programs in the course using Eclipse IDE and Java programming. Theory will be intermixed with practice so that you implement what you have learned as a developer. You will write more than thirty programs during this course.
Only way to learn a new tool quickly is to practice by writing programs. This course provides you the right mix of theory and practice with real life industry use of Apache Storm. By enrolling in this course, you will be on a journey to become a big data developer using Apache Storm.
