💥 Introduction

Flyte is a structured programming and distributed processing platform that enables highly concurrent, scalable and maintainable workflows for Machine Learning and Data Processing. It is a fabric that connects disparate computation backends using a type safe data dependency graph. It records all changes to a pipeline, making it possible to rewind time. It also stores a history of all executions and provides an intuitive UI, CLI and REST/gRPC API to interact with the computation.

Flyte is more than a workflow engine -- it uses a workflow as a core concept and a task (a single unit of execution) as a top level concept. Multiple tasks arranged in a data producer-consumer order create a workflow.

Workflows and Tasks can be written in any language, with out of the box support for Python, Java and Scala.

⏳ Five Reasons to Use Flyte

  • Kubernetes-Native Workflow Automation Platform
  • Ergonomic SDK's in Python, Java & Scala
  • Versioned & Auditable
  • Reproducible Pipelines
  • Strong Data Typing

🚀 Quick Start

With docker installed, run the following command:

  docker run --rm --privileged -p 30081:30081 -p 30084:30084 cr.flyte.org/flyteorg/flyte-sandbox

This creates a local Flyte sandbox. Once the sandbox is ready, you should see the following message: Flyte is ready! Flyte UI is available at http://localhost:30081/console.

Visit http://localhost:30081/console to view the Flyte dashboard.

Here's a quick visual tour of the console.

🔥 Features

  • Used at Scale in production by 500+ users at Lyft with more than 1 million executions and 40+ million container executions per month
  • A data aware platform
  • Enables collaboration across your organization by:
    • Executing distributed data pipelines/workflows
    • Reusing tasks across projects, users, and workflows
    • Making it easy to stitch together workflows from different teams and domain experts
    • Backtracing to a specified workflow
    • Comparing results of training workflows over time and across pipelines
    • Sharing workflows and tasks across your teams
    • Simplifying the complexity of multi-step, multi-owner workflows
  • Quick registration -- start locally and scale to the cloud instantly
  • Centralized Inventory constituting Tasks, Workflows and Executions
  • gRPC / REST interface to define and execute tasks and workflows
  • Type safe construction of pipelines -- each task has an interface which is characterized by its input and output, so illegal construction of pipelines fails during declaration rather than at runtime
  • Supports multiple data types for machine learning and data processing pipelines, such as Blobs (images, arbitrary files), Directories, Schema (columnar structured data), collections, maps, etc.
  • Memoization and Lineage tracking
  • Provides logging and observability
  • Workflow features:
    • Start with one task, convert to a pipeline, attach multiple schedules, trigger using a programmatic API, or on-demand
    • Parallel step execution
    • Extensible backend to add customized plugin experience (with simplified user experience)
    • Branching
    • Inline subworkflows (a workflow can be embeded within one node of the top level workflow)
    • Distributed remote child workflows (a remote workflow can be triggered and statically verified at compile time)
    • Array Tasks (map a function over a large dataset -- ensures controlled execution of thousands of containers)
    • Dynamic workflow creation and execution with runtime type safety
    • Container side plugins with first class support in Python
    • PreAlpha: Arbitrary flytekit-less containers supported (RawContainer)
  • Guaranteed reproducibility of pipelines via:
    • Versioned data, code and models
    • Automatically tracked executions
    • Declarative pipelines
  • Multi cloud support (AWS, GCP and others)
  • Extensible core, modularized, and deep observability
  • No single point of failure and is resilient by design
  • Automated notifications to Slack, Email, and Pagerduty
  • Multi K8s cluster support
  • Out of the box support to run Spark jobs on K8s, Hive queries, etc.
  • Snappy Console
  • Python CLI and Golang CLI (flytectl)
  • Written in Golang and optimized for large running jobs' performance
  • Grafana templates (user/system observability)

In Progress

  • Helm chart for Flyte (coming soon - June)
  • Flink-K8s (coming soon - June)
  • One click deploy to AWS
  • Reactive pipelines & Events
