Spark introduces a programming module for structured data processing called Spark SQL. It provides a programming abstraction called DataFrame and can act as distributed SQL query engine. Features of Spark SQL. The following are the features of Spark SQL − Integrated − Seamlessly mix SQL queries with Spark programs.

Spark is a unified data processing engine that can be used to stream and batch process data, apply machine learning on large datasets, etc. Spark is not suitable for use in a multi-user the environment at the moment. Spark SQL and the DataFrames API supports several programming languages, including Python, R, Scala, and Java. Spark SQL, Presto, and Hive all support query of large-scale data residing in distributed storage using SQL syntax, but they are used for different scenarios. Spark SQL is the core module in Spark, while Presto is in the Hadoop ecosystem.

Hive Limitations Apache Hive was originally designed to run on top of Apache Spark . Apache Spark SQL is a Spark module to simplify working with structured data using DataFrame and DataSet abstractions in Python, Java, and Scala. These abstractions are the distributed collection of data organized into named columns. It provides a good optimization technique.

Spark SQL was built to overcome these drawbacks and replace Apache Hive. Spark SQL or previously known as Shark (SQL on Spark)is an Apache Spark module for structured data processing.

Spark SQL is Spark's interface for working with structured and semi-structured data. Structured data is considered any data that has a schema such as JSON,

We mentioned Spark SQL and now we want you to do some hands-on practice. The first thing we're going to do is get you familiar with and get you set up with Databricks Community Edition. Now Databricks Community Edition is what you'll be using to complete all of the hands on components of this module. Essentially, Spark SQL leverages the power of Spark to perform distributed, robust, in-memory computations at massive scale on Big Data. Spark SQL provides state-of-the-art SQL performance, and also maintains compatibility with all existing structures and components supported by Apache Hive (a popular Big Data Warehouse framework) including data formats, user-defined functions (UDFs) and the Language API − Spark is well-matched with different languages and Spark SQL. It is also, supported by these languages- API (python, scala, java, HiveQL).
