Summary
In this chapter, we learned about the fundamentals of Spark, got an introduction to Databricks, and explored Delta Lake. We were introduced to Azure Databricks and the important workspace components. We learned how to create an Azure Databricks instance, a notebook in the Databricks workspace, Spark clusters, and Databricks jobs. We also learned about the important big data file formats such as Parquet, Avro, and ORC. We also learned about the fundamentals of Delta Lake and went through a worked-out example.
In the next chapter, we will dive deeper into the concepts of batch and stream processing in Azure Databricks. We'll also see more examples in the chapter to practice working hands-on in a Databricks environment.
