SQL Serverless and Spark Clusters
Data exploration often consists of running a series of queries against raw data to grasp its structure and content, keeping in mind the need to plan the transformations required to make it feasible for data analysis. Azure offers many tools that can be used for this purpose, particularly Synapse Analytics Serverless SQL pool and the various implementations of Apache Spark, such as Synapse Spark and Databricks.
Note
This section primarily focuses on the Creating and executing queries by using a compute solution that leverages SQL serverless and Spark cluster topic of the DP-203: Data Engineering on Microsoft Azure exam.
Starting with Synapse Analytics Serverless pool, the easiest way to introduce the Serverless SQL pool is by comparing and contrasting it with the other options available in Synapse to run SQL pools – for example, dedicated SQL pools. The SQL server instances consist of clusters (pool and cluster can be considered synonyms...
