Tons of companies, including Fortune 500 companies, are adapting Apache Spark Streaming to extract meaning from massive data streams; today, you have access to that same big data technology right on your desktop. In this article. In this PySpark Tutorial, we will understand why PySpark is becoming popular among data engineers and data scientist. However, this tutorial can work as a standalone tutorial to install Apache Spark 2.4.7 on AWS and use it to read JSON data from a Kafka topic. It is because of a library called Py4j that they are able to achieve this. In this article. In general, most developers seem to agree that Scala wins in terms of performance and concurrency: it’s definitely faster than Python when you’re working with Spark, and when you’re talking about concurrency, it’s sure that Scala and the Play framework make it easy to write clean and performant async code that is easy to reason about. Audience Spark Streaming is a scalable, high-throughput, fault-tolerant streaming processing system that supports both batch and streaming workloads. This step-by-step guide explains how.
