Customer Success

Infinome Biosciences

Infinome Bio is a biotech startup working toward a sustainable bio-enabled future, using advancements in gene editing and lean bioengineering to unlock the potential of synthetic biology for highly scalable, safer, affordable and accessible solutions.

Data Scientist Krishna Yerramsetty talked to us about Infinome’s journey with Flyte, highlighting some challenges that the industry faced, how Flyte offers features that drastically cut processing time, and why Flyte was the right fit for them. According to Krishna:

“Biology is always the bottleneck. It’s hard, so we want to make life easier for data scientists. Even if that means sometimes custom pipelines need to be built, or we need to spend a lot of time trying to make a workflow file format easily readable by biologists, that’s definitely what we want to do. We don’t want to take shortcuts for data science and make life easy for biology, and that’s where I think Flyte really really shines for us.”

Flyte’s Latest Releases

Flyte v1.2.0 was released on Oct. 3!

The most notable feature of this release, Flyte’s Ray integration, was thanks to valuable contributions from Spotify — one of Flyte’s earliest customers — who identified a pain point, talked to us, and worked with us on feature requests and PRs that resulted in Flyte improvements with significant performance gains.

The Ray integration supports large nested and dynamic workflows so they can be shared across teams or implemented as part of even bigger workflows. It can now reduce the size of Kubernetes resources for large Flyte workflows, by having FlyteAdmin write parts of the CRD to storage before it creates the Flyte workflow resource on Kubernetes. FlytePropeller then reads the CRD parts when handling the Flyte workflow resource. Learn more on the Ray integration in the blog Ray and Flyte: Distributed Computing and Orchestration by Kevin Su.

In addition to Ray support, v1.2.0 includes:

  • Perf improvements
  • Two Flytekit plugins: DBT plugin and hugging face
  • Improvements to CLIs, including changes to PyFlyte Run

This is How We Do it
