This self-paced guide is the “Hello World” tutorial for Apache Spark using Databricks. In the following tutorial modules, you will learn the basics of creating Spark jobs, loading data, and working with data. You’ll also get an introduction to running machine learning algorithms and working with streaming data. Databricks lets you start writing Spark queries instantly so you can focus on your data problems.
Hover over the above navigation bar and you will see the six stages to getting started with Apache Spark on Databricks. This guide will first provide a quick start on how to use open source Apache Spark and then leverage this knowledge to learn how to use Spark DataFrames with Spark SQL. We also will discuss how to use Datasets and how DataFrames and Datasets are now unified. The guide also has quick starts for Machine Learning and Streaming so you can easily apply them to your data problems. Each of these modules refers to standalone usage scenarios—including IoT and home sales—with notebooks and datasets so you can jump ahead if you feel comfortable.
Apache Spark is a powerful open-source processing engine built around speed, ease of use, and sophisticated analytics.
Many data scientists, analysts, and general business intelligence users rely on interactive SQL queries for exploring data. Spark SQL is a Spark module for structured data processing. It provides a programming abstraction called DataFrames and can also act as distributed SQL query engine. It enables unmodified Hadoop Hive queries to run up to 100x faster on existing deployments and data. It also provides powerful integration with the rest of the Spark ecosystem (e.g., integrating SQL query processing with machine learning).
Many applications need the ability to process and analyze not only batch data, but also streams of new data in real-time. Running on top of Spark, Spark Streaming enables powerful interactive and analytical applications across both streaming and historical data, while inheriting Spark’s ease of use and fault tolerance characteristics. It readily integrates with a wide variety of popular data sources, including HDFS, Flume, Kafka, and Twitter.
Machine learning has quickly emerged as a critical piece in mining Big Data for actionable insights. Built on top of Spark, MLlib is a scalable machine learning library that delivers both high-quality algorithms (e.g., multiple iterations to increase accuracy) and blazing speed (up to 100x faster than MapReduce). The library is usable in Java, Scala, and Python as part of Spark applications, so that you can include it in complete workflows.
GraphX is a graph computation engine built on top of Spark that enables users to interactively build, transform and reason about graph structured data at scale. It comes complete with a library of common algorithms.
Spark Core is the underlying general execution engine for the Spark platform that all other functionality is built on top of. It provides in-memory computing capabilities to deliver speed, a generalized execution model to support a wide variety of applications, and Java, Scala, and Python APIs for ease of development.
“At Databricks, we’re working hard to make Spark easier to use and run than ever, through our efforts on both the Spark codebase and support materials around it. All of our work on Spark is open source and goes directly to Apache.”
