➡️ Welcome to the Ultimate Apache Spark for Java Developers Course
- Apache Spark is the next-generation batch and stream processing engine.
- It's been proven to be almost 100 times faster than Hadoop and much much easier to develop distributed big data applications with.
- It's demand has skyrocketed in recent years and having this technology on your resume is truly a game changer.
- Over 3000 companies are using Spark in production right now and the list is growing very quickly!
- Some of the big names include: Oracle, Hortonworks, Cisco, Verizon, Visa, Microsoft, and Amazon as well as most of the big world banks and financial institutions!

➡️ Below are some of the things you'll learn:
- How to develop Spark Java Applications using Spark SQL Dataframes
- Understand how the Spark Standalone cluster works behind the scenes
- How to use various transformations to slice and dice your data in Spark Java
- How to marshall/unmarshall Java domain objects (pojos) while working with Spark Datasets
- Master joins, filters, aggregations and ingest data of various sizes and file formats (txt, CSV, JSON etc.)
- Analyze over 18 million real-world comments on Reddit to find the most trending words used
- Develop programs using Spark Streaming for streaming stock market index files
- Stream network sockets and messages queued on a Kafka cluster
- Learn how to develop the most popular machine learning algorithms using Spark MLlib
- Also, understand the older Java RDD (resilient distributed datasets) API and know how it defers from Datasets and Dataframes.
