Unlock the full self-paced class from Databricks Academy! Introduction to Data Science and Machine Learning (AWS Databricks) https://academy.databricks.com/.. What is Apache Spark. Apache Spark provides primitives for in-memory cluster computing. A Spark job can load and cache data into memory and query it repeatedly. In-memory computing is much faster than disk-based applications. Spark also integrates with multiple programming languages to let you manipulate distributed data sets like local collections. There's no need to structure everything as map and reduce operations Apache Spark™ is a general-purpose distributed processing engine for analytics over large data sets—typically terabytes or petabytes of data. Apache Spark can be used for processing batches of data, real-time streams, machine learning, and ad-hoc query. Processing tasks are distributed over a cluster of nodes, and data is cached in-memory.

Recognizing this problem, researchers developed a specialized framework called Apache Spark. The key idea of spark is Resilient Distributed Datasets (RDD); it supports in-memory processing computation. This means, it stores the state of memory as an object across the jobs and the object is sharable between those jobs. Data sharing in memory is 10 to 100 times faster than network and Disk Koalas: pandas API on Apache Spark¶. The Koalas project makes data scientists more productive when interacting with big data, by implementing the pandas DataFrame API on top of Apache Spark. pandas is the de facto standard (single-node) DataFrame implementation in Python, while Spark is the de facto standard for big data processing Apache Spark is a parallel processing framework that supports in-memory processing to boost the performance of big-data analytic applications.

One of the well-known problems in parallel computational systems is data skewness. Usually, in Apache Spark, data skewness is caused by transformations that change data partitioning like join, groupBy, and orderBy. For example, joining on a key that is not evenly distributed across the cluster, causing some partitions to be very large and not allowing Spark to process data in parallel. Since this is a well-known problem.
