Apache Spark is an open-source cluster-computing framework. It provides elegant development APIs for Scala, Java, Python, and R that allow developers to execute a variety of data-intensive workloads across diverse data sources including HDFS, Cassandra, HBase, S3 etc. Historically, Hadoop’s Map...
Spark was originally written by the founders of Databricks during their time at UC Berkeley. The Spark project started in 2009, was open sourced in 2010, and in 2013 its code was donated to Apache, becoming Apache Spark. The employees of Databricks have written over 75% ...
Spark supports SQL queries, machine learning, stream processing, and graph processing. Additional Resources About Apache Spark Learning Apache Spark 2nd Edition eBook 8 Steps for a Developer to Learn Apache Spark with Delta Lake eBook Databricks Inc. ...
Apache Spark is a fast and general purpose analytics engine for large-scale data processing, that runs on Hadoop, Apache Mesos, Kubernetes, standalone, or in the cloud. Spark offers high-level operators that make it easy to build parallel applications in Scala, Python, R, or SQL, using an...
Introduction to Apache Spark: With Resilient Distributed Datasets, Spark SQL, Structured Streaming and Spark Machine Learning libraryThere is no better time to learn Spark than now. Spark has become one of the critical components in the big data stack because of its ease of use, speed, and ...
Another important aspect when learning how to use Apache Spark is the interactive shell (REPL) which it provides out-of-the box. Using REPL, one can test the outcome of each line of code without first needing to code and execute the entire job. The path to working code is thus much sho...

Introduction to Apache Spark Apache Spark is an open source framework for processing large datasets stored in heterogeneous data stores in an efficient and fast way. Sophisticated analytical algorithms can be easily executed on these large datasets. Spark can execute a distributed program 100 times fas...
Apache Spark is a lightning-fast cluster computing technology, designed for fast computation. It is based on Hadoop MapReduce and it extends the MapReduce model to efficiently use it for more types of computations, which includes interactive queries and stream processing. The main feature of Spark...
Apache Spark is a computing framework for processing big data, and Spark SQL is a component of Apache Spark. This four-hour course will show you how to take Spark to a new level of usefulness, using advanced SQL features, such as window functions. Over the course of four chapters, you...
