Numaflow

Summary

Numaflow is a Kubernetes-native tool for running massively parallel stream processing. A Numaflow Pipeline is implemented as a Kubernetes custom resource and consists of one or more source, data processing, and sink vertices.

Numaflow installs in a few minutes and is easier and cheaper to use for simple data processing applications than a full-featured stream processing platforms.

Key Features

• Kubernetes-native: If you know Kubernetes, you already know how to use Numaflow.
• Language agnostic: Use your favorite programming language.
• Exactly-Once semantics: No input element is duplicated or lost even as pods are rescheduled or restarted.
• Auto-scaling with back-pressure: Each vertex automatically scales from zero to whatever is needed.

Data Integrity Guarantees:

• Minimally provide at-least-once semantics
• Provide exactly-once semantics for unbounded and near real-time data sources
• Preserving order is not required

Roadmap

• Data aggregation (e.g. group-by)

Types

type Version

type Version struct {
	Version      string
	BuildDate    string
	GitCommit    string
	GitTag       string
	GitTreeState string
	GoVersion    string
	Compiler     string
	Platform     string
}

Version contains version information

func GetVersion

func GetVersion() Version

GetVersion returns the version information

func (Version) String

func (v Version) String() string

String outputs the version as a string
