Amazon Athena is a service that lets you run SQL queries against structured data files stored in S3. It takes a “divide and conquer” approach, spinning up parallel query execution engines that each examine only a portion of your data. The performance of these queries, however, depends on how you consolidate and partition your data. In this post I compare query times for a moderately large dataset, looking for the “sweet spot” between number of files and individual file size.
Scale Your Data Pipeline Efficiently
It can be a struggle to extract business value from your data. Disparate data sources and data quality are just a few of the complex issues you face.
Ensure that the entire pipeline of your data collection yields accurate, consistent results. When you partner with Chariot’s experienced data engineers, you develop highly optimized data pipelines that yield valuable business insights. From collection to analytics to preparation, your pipeline’s plumbing should withstand the digital flood.

Clickstream data – the behavior data collected from a user’s path through a website or app – is often used for business intelligence reports. It helps many companies answer questions…
In my last post I discussed how an artifact server is the best way to publish locally-developed Python packages. In this post, I show you how to set up the AWS CodeArtifact service and use it with pip and Poetry.
Coming from a Java background, I consider the Python development process to be a bit of a mess. The pieces are all there: a central repository for publicly-available packages, a way to install the packages you want, and several ways to run your program with only those packages. But it seems that everybody has a different way to combine those pieces. So when a colleague introduced me to Poetry, my first reaction was “oh great, another tool that solves part of my problem.” But after spending time with it, I don’t want to build Lambdas any other way.
