It is important to stay ahead of the curve and keep services up to date. That’s why we encourage all Azure Synapse customers with Apache Spark workloads to migrate to the newest GA version, Azure Synapse Runtime for Apache Spark 3.4 . The update brings Apache Spark to version 3.4 and Delta Lake to version 2.4, introduces Mariner as the new operating system, and updates Java from version 8 to 11.
