Feathr provides enterprises with a platform for data engineering and AI workflows.
About Feathr
Feathr is an open-source data and AI engineering platform for enterprise use. It was used in production at LinkedIn for several years and was open sourced in 2022. It is now a project under the LF AI & Data Foundation.
With Feathr, you can define data and feature transformations on batch and streaming data sources using Python-based APIs. You can register transformations by name, retrieve transformed data for uses such as AI modeling, compliance, and go-to-market, and share them across a team or company. It computes feature transformations and joins them to training data with point-in-time-correct semantics, and supports materializing and deploying features for online production use.
Feathr suits data scientists, data engineers, and enterprise teams that work with offline batch, streaming, and online environments. It includes a built-in registry, a UI, a self-contained sandbox container for testing, and integrations with Databricks and Azure Synapse.
