Course Description
Spark is an analytics engine built on Hadoop that can be used for working with big data, data
science and processing batch and streaming data. In this course you will discover how to develop applications in Spark to work with streaming data and explore the different ways to process streams and generate an output.
Learning Objectives
Streaming Data Architectures: Processing Streaming Data
- Course Overview
- install the latest available version of PySpark
- configure a streaming data source using Netcat and write an application to process the stream
- describe the effects of using the Update mode for the output of your stream processing application
- write an application to listen for new files being added to a directory and process them as soon as they come in
- compare the Append output to the Update mode and distinguish between the two
- develop applications that limit the files processed in each trigger and use Spark's Complete mode for the output
- perform aggregation operations on streaming data using the DataFrame API
- work with Spark SQL in order to process streaming data using SQL queries
- define and apply standard, re-usable transformations for streaming data
- recall the key ways to use Spark for streaming data and explore the ways to process streams and generate output
