The new Golang v1.16 embed directive helps us keep a single binary and bundle out static content. This post will cover how to work with embed directive by applying it to a demo application. Why Embed One of the benefits of using Go is having your application compiled into a single self-contained binary. Having a …
The quality of the data we introduce determines the overall reliability of our data lake. And the ingestion stage is a critical point for ensuring the soundnes of our service and data. The same way software engineers apply automatic testing to new code, data engineers should continuously test newly ingested data while ensuring they meet …

Lists are everywhere. And there’s a good reason for that: lists have an order to them. They reduce our stress by assuring us that everything is written down on paper (read: note app), and that we are keeping track of things that we would otherwise forget. People who adopt minimalist lifestyles often make complete lists …
lakeFS is an open source tool that delivers resilience and manageability to object-storage based data lakes. lakeFS provides Git-like operations over your MinIO storage environment and works seamlessly with all modern data frameworks such as Spark, Hive, Presto, Kafka, R and Native Python etc. Common use-cases include creating a development environment without copying or mocking …
The demand for infrastructure that contributes to the collection, storage, and analysis of data is growing with the increasing amounts of data managed by organizations. Every organization that manages data pipelines to extract insights from data encounters the need for reproducibility, safe experimentation, and means to ensure data quality. The path to answering these needs …

TL;DR With some thoughtful engineering, we can achieve a lot of the benefits that come with a microservice oriented architecture, while retaining the simplicity and low operating cost of being a monolith. What is lakeFS? lakeFS is an open source tool that delivers resilience and manageability to object-storage based data lakes. lakeFS provides Git-like capabilities …

The data mesh paradigm The Data Mesh paradigm was first introduced by Zhamak Dehghani in her article How to Move Beyond a Monolithic Data Lake to a Distributed Data Mesh. Unlike traditional monolithic data infrastructures that handle the consumption, storage, transformation, and output of data in one central data lake, a data mesh supports distributed, …

While Object Storage is not novel technology, it can still be overwhelming when getting started. Here’s a definitive guide to object-based storage with everything you need to know. What is object storage? At its core, object storage or object-based storage represents a data storage architecture that allows you to store large amounts of unstructured data …
Modern Data Lakes are a complexity tar pit. They involve many moving parts: distributed computation engines, running on virtualized servers connected by a software defined network, running on top of distributed object stores, orchestrated by a distributed stream processor or pipeline execution engine. These moving parts fail. All the time. Handling these failures is not …
Overview In this article, I will try to cover some do’s and don’ts for system testing from the perspective of an open-source project. To keep things simple, it all boils down to running the system as our customers would: think of the different use-cases of your system, the environment where it runs, the configuration options, …
