My talk for PASS Summit 2023 is about how to load data incrementally, such as from Change Data Feed or streaming a log of events. Below are some additional thoughts and links to resources for easy reference. Presentation description: There has been an increasing push to load data incrementally throughout the day or even within… Continue Reading
I had the privilege to present for Creating Coding Careers, a great organization in the San Diego area that helps people get established in tech careers via apprenticeships and other programs. Above are the slides used in that presentation.

If you choose to use Snowflake along with Azure for your data platform, you will have to make choices on how to load the data. Landing processed data into your data lake on Azure Data Lake Storage Gen2 (ADLS) is the first step that I recommend in most environments. I like this pattern because then… Continue Reading
Snowflake, like similar analytic databases, has a fast way to load data from files. The COPY command can quickly read files and append the records to a table. It does this by reading from an external stage which points to a cloud storage location. This currently supports Azure Storage, Amazon S3, and Google Cloud Storage.… Continue Reading
If we want to kick off a single Apache Spark notebook to process a list of tables we can write the code easily. The simple code to loop through the list of tables ends up running one table after another (sequentially). If none of these tables are very big, it is quicker to have Spark load tables concurrently (in parallel) using threads. There are some different options of how to do this, but I am sharing the easiest way I have found when working with a notebook in Databricks, Azure Synapse Spark, Jupyter, or Zeppelin.
In this post I introduce some of the core capabilities of Azure Synapse Analytics and when they are used. I present from the perspective of data engineer but it should be easy to translate what is most useful for analysts and data scientists also. Please continue reading for a quick walkthrough of the capabilities and… Continue Reading
For production uses of Azure Synapse there are benefits to implementing Continuous Integration (CI) and Continuous Deployment (CD). Implementing CI/CD includes the need to deploy the Azure infrastructure in an automated way. In this post, I share things I learned that may be helpful for you. I also have a few links to other content that was helpful for me to get an environment setup.
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
When working with an Apache Spark environment you may need to install third party libraries or custom packages. In this post I share the steps for installing Java or Scala libraries to Azure Synapse serverless Apache Spark pools. For Java or Scala code the libraries are packaged as JAR files that you add to the… Continue Reading
Real-time data processing is becoming more common in companies of all sizes. The use cases range from simple stream ingestion to complex machine learning pipelines. If you need to get started with streaming in Azure, Stream Analytics gives you a simple way to get up and running. Most of my streaming projects involve Apache Kafka and Spark which can take a lot of setup (or at least involving additional vendors to simplify the experience). Those technologies are great especially for challenging streaming pipelines, but if your data platform is within Azure you should consider if Stream Analytics will meet your needs.
