Batch processing is the method of executing high volume, repetitive data jobs at certain intervals(hourly, daily) of time in groups/batches. It can be usually done at non-peak times like the end of the day or overnight. If the task is requiring minimum human intervention, and would be mo...

3 PySpark SQL & DataFramesCommencer le chapitre In this chapter, you'll learn about Spark SQL which is a Spark module for structured data processing. It provides a programming abstraction called DataFrames and can also act as a distributed SQL query engine. This chapter shows how Spark SQL al...
This powerful interactive processing is yet another advantage of Spark over other Big Data processing frameworks.Also notice the splitting of the data into the training and test dataset using the randomSplit function. The idea there is to create an ML model using the data in train...
