Optimizing Delta Lake tables

To optimize Delta Lake tables, we will focus on improving performance and reducing storage space. We’ll cover various techniques and strategies that can be applied to enhance the efficiency of Delta Lake tables.

How to do it...

1. Import the required libraries: Start by importing the necessary libraries for working with Delta Lake. In this case, we need the delta module and the SparkSession class from the pyspark.sql module:

   from delta import configure_spark_with_delta_pip, DeltaTable

   from pyspark.sql import SparkSession

2. Create a SparkSession object: To interact with Spark and Delta Lake, you need to create a SparkSession object:

   builder = (SparkSession.builder

                  .appName("optimize-delta-table")

                  .master("spark://spark-master:7077")
