Spark Streaming & foreachBatch

Spark Streaming is a powerful tool for processing streaming data. It allows you to process data as it arrives, without having to wait for the entire dataset to be available. This can be very useful for applications that need to respond to changes in data in real time.

One of the features of Spark Streaming is the foreachBatch() method. This method allows you to apply a custom function to each batch of data as it arrives. This can be useful for a variety of tasks, such as:

• Filtering data
• Transforming data
• Writing data to a database
• Sending data to an external system

The foreachBatch() method is a powerful tool that can be used to extend the capabilities of Spark Streaming. In this blog post, we will take a closer look at how to use foreachBatch().
