Spark has come to dominate the big data processing space in a short span of time since its release and now serves as the de-facto unified big data processing engine in the industry. 

In this course, you will get a complete introduction to the basics of Spark. You will start by learning about the architecture, the application lifecycle, and its API.

From there, you will dive into the data frame data structure and its API as well as the strongly-typed datasets API. Lastly, you’ll get into the Spark SQL engine which will allow you to issue queries on structured data with a schema.

By the end of this course, you will have the confidence to use Spark in any of your big data projects.

An Introduction to Spark

## Datasets
<p>Below is the definition of a Dataset from the official Databricks documentation: 

> *"A Dataset is a strongly-typed, immutable collection of objects that are mapped to a relational schema. Datasets are a type-safe structured API available in statically typed, Spark supported languages Java and Scala. Datasets are strictly a JVM language feature. Datasets aren't supported in R and Python since these languages are dynamically typed languages".*

 After Spark 2.0, RDD was replaced by Dataset, which is strongly-typed like an RDD, but with richer optimizations under the hood.
