Monitor Synapse Spark with Log Analytics

Log Analytics provides a way to easily query Spark logs and setup alerts in Azure. This provides a huge help when monitoring Apache Spark. In this video I walk through the setup steps and quick demo of this capability for the Azure Synapse Spark log4j output. I include written instructions and troubleshooting guidance in this… Continue Reading

Azure Synapse Spark: External Python Packages

When working with an Apache Spark environment you may need to install external libraries or custom packages. In this post I share the steps for installing Python packages to Azure Synapse serverless Apache Spark pools. For Python code the libraries are packages as wheel (.whl) files. You can also install Python packages that are available… Continue Reading
