lakeFS Acquires DVC, Uniting Data Version Control Pioneers to Accelerate AI-Ready Data
Introduction We recently released the first version of lakeFS supported by Pebble’s sstable library – RocksDB. The release introduced a new data model which is now much closer to Git. Instead of using a PostgreSQL server that quickly becomes a bottleneck, committed metadata now lives on the object store itself. Early on we realized that […]
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
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
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,
Overview As part of our routine work with data we develop code, choose and upgrade compute infrastructure, and test new data. Usually, this requires running parts of our production pipelines in parallel to production, testing the changes we wish to apply. Every data engineer knows that this convoluted process requires copying data, manually updating configuration,
Lakeview is a new open source visibility tool for AWS S3 based data lakes. Think of it as ncdu, but for Petabyte-scale data. It’s goal is to provide you with an easy way to see the total size of your S3 bucket (prefix) storage. Instead of scanning billions of objects using the S3 API, which
50 years ago it was very hard to collaborate over code. When developing large scale software projects it was difficult to manage changes to source code over time, as revision control tools were only starting to enter mainstream computing. The adoption of version control tools, first centralized and then distributed, changed all that, and now
