Effective Remote Work

I'm a believer in remote work as a great enabler of more opportunity and greater productivity. Here are my tips for working remote effectively, including how those in the office can best enable their distributed team members.


Data Lake Introduction

Hearing a lot of mention of Data Lakes but still not sure what that means or why anyone cares? This video will cover a brief introduction to what a Data Lake is and why so many organizations are adding them to their analytics ecosystem. To show what interacting with a data lake may look like for a typical data analyst, I included a demo of how you would use Spark SQL to query the data lake from Azure Databricks.


Create Service Principal in Azure Portal

If you are working with Azure Databricks (or many other Azure resources), you may come across the need for a Service Principal in order to configure access to different resources. The steps are fairly straight forward but the terminology is not consistent so this video will walk through the steps and describe where to find the values to use when you authenticate.

Spark Streaming with Azure Databricks

In the world of data science we often default to processing in nightly or hourly batches, but that pattern is not enough any more.  Our customers and business leaders see information is being created all the time and realize it should be available much sooner.  While the move to stream processing adds complexity, the tools we have available make it achievable for teams of any size.

This presentation covers why we need to shift some of our workloads from batch data jobs to streaming in real-time.  We dive into how Spark Structured Streaming in Azure Databricks enables this along with streaming data systems such as Kafka and EventHub. We will discuss the concepts, how Azure Databricks enables stream processing, and review code examples on a sample data set.


Delta Lake on Azure Databricks

With the shift to data lakes that use distributed file storage as the foundation, we have been missing the reliability that relational databases provides. Databricks Delta is a data management system focused on bringing more reliability and performance into our data lakes. It sits on top of existing storage and the API is very similar to reading and writing to files from Spark already. This session will present the overview of Delta Lake, why it may be a better option than standard data lake storage, and how you can use it from Azure Databricks.
