Feast 0.15

We released a new version of Feast! A big thanks to those contributing to the release. This release introduces:
  • [Experimental] Push-based streaming support (docs): users can push streaming data into online stores for fresher features at serving time.
  • Entity aliasing (docs): improved support for cases when an entity (e.g. "user") has different column names in different source tables (e.g. "spammer", "reporter").
  • Feature Transformation Server: a server that executes on demand transformations. The existing feature server (e.g. deployed with AWS Lambda) executes on demand transformations already. This new server integrates with Feast Serving (java server) for latency sensitive use cases.
  • Easy way to test offline/online store plugins using the existing Feast test suite. See docs for details.

 If you have questions on any of these, please reach out to the Feast team!

Community contribution highlights

Work in progress

Low latency serving

The team has profiled a sample scenario in using Feast Serving with on demand feature views for large batch sizes and found action items to improve serving performance. See details in On-Demand Transformations Latency Investigation.
