Combining lakeFS and Spark provides a new standard for scale and elasticity to distributed data pipelines. When integrating two technologies, the aim should be to expose the strengths of each as much as possible. With this philosophy in mind, we are excited to announce the beta release of the lakeFS FileSystem! This native Hadoop FileSystem …

Debugging an issue is never fun, but why make it harder? In this post, we show how reproducing data is possible whether interacting with a single file, entire table, or data repository. Introducing Data Reproducibility There are two types of issues in the world — reproducible and unreproducible. A reproducible issue is one where the original conditions for …
Let’s start with the obvious: the lakeFS project doesn’t exist in isolation. It belongs to a larger ecosystem of data engineering tools and technologies adjacent and complementary to the problems we are solving. What better way to visualize our place in this ecosystem, I thought, than by creating a cross-sectional LUMAscape to depict it. What’s …
It makes perfect sense that if you type aws s3 ls s3://my-bucket to list the contents of an S3 bucket, you would expect to connect to the genuine bucket and have its contents listed. But there’s no hard rule that you have to connect to the real bucket. And in fact, there’s a simple parameter …
Introduction When building a data lake, there is perhaps no more consequential decision than the format data will be stored in. The outcome will have a direct effect on its performance, usability, and compatibility. It is inspiring that by simply changing the format data is stored in, we can unlock new functionality and improve the …

Rid yourself of these troubling habits and start the journey towards data lake mastery! Introduction Data lakes offer tantalizing performance upside, which is a major reason for their high rate of adoption. Sometimes though, the promise of technological performance can overshadow an unpleasant developer experience. This is troublesome since I believe the developer experience is as …
What is a Data Lake? A data lake is a system of technologies that allow for the querying of data in file or blob objects. When employed effectively, they enable the analysis of structured and unstructured data assets at tremendous scale and cost-efficiency. The number of organizations employing data lake architectures has increased exponentially since …
