Exploring the Apache Spark Structured Streaming API for Processing Streaming Data

  • by Handson
  • Course level: All Levels

Description

Stream processing applications work with continuously updated data and react to changes in real-time. In this course, Exploring the Apache Spark Structured Streaming API for Processing Streaming Data, you’ll focus on using the tabular data frame API as well as Spark SQL to work with streaming, unbounded datasets using the same APIs that work with bounded batch data.

First, you’ll explore Spark’s support for different data sources and data sinks, understand the use case for each and also understand the fault-tolerance semantics that they offer. You’ll write data out to the console and file sinks, and customize your write logic with the foreach and foreachBatch sinks.

Next, you’ll see how you can transform streaming data using operations such as selections, projections, grouping, and aggregations using both the DataFrame API as well as Spark SQL. You’ll also learn how to perform windowing operations on streams using tumbling and sliding windows. You’ll then explore relational join operations between streaming and batch sources and also learn the limitations on streaming joins in Spark.

Finally, you’ll explore Spark’s support for managing and monitoring streaming queries using the Spark Web UI and the Spark History server.

When you’re finished with this course, you’ll have the skills and knowledge to work with different sources and sinks for your streaming data, apply a range of processing operations on input streams, and perform windowing and join operations on streams.
