Presentation about OpenFeature
KubeCon main entrance
Back from an incredible week at #KubeCon London! I loved connecting with fellow tech enthusiasts. Special shoutout to our @openfeature.dev team for sharing insights on feature flagging. Our project discussions were enlightening! Great to meet the folks @github.com. #CloudNative #OpenFeature
What’s new in @openfeature.dev? Today these updates were announced at #KubeCon + #CloudNativeCon and more!
Which update are you most excited about?
#dynatraceatkubecon #openfeature
Giulia from the DevRel team at Dynatrace will take you on a trip to #KubeCon + #CloudNativeCon London 2025.
Stay tuned for updates on what's happening in the cloud-native world, particularly with #OpenTelemetry and #OpenFeature.

I'm speaking today at #KubeCon London, as part of the #OpenFeature summit. Come hear my talk, Beyond Boolean, where I discuss some of the challenges teams face when flagging at scale and how we help you solve those problems at @growthbook.io
*8d -> #KubeCon & a bit of #OpenFeature a day #16*
#OFREP is short for OpenFeature #Remote #Evaluation #Protocol. It is a protocol specification for the #communication between #providers and feature flag management systems that support it.
Find it on github.com/open-feature/protocol
*10d -> #KubeCon & a bit of #OpenFeature a day #15*
With the specification of the #TrackingAPI, we can tie application #metrics & the feature flag system together; without requiring a vendor to support flag #analytics or having 2 separate systems; we can send all data to the same analytics backend!
*12d -> #KubeCon & a bit of #OpenFeature a day #14*
TIL: using the #OpenTelemetry #protocol ( #OTLP ) applications can be instrumented to send #telemetry data to analytics backends. This even works when running the app #locally!
Pro tip: set the env var 'OTEL_LOG_LEVEL=debug' for development
*17d -> #KubeCon & a bit of #OpenFeature a day #13*
The OF #project consists of >40 #repositories. Most essential to the standard are:
/spec: contains the standardization
/*-sdk repos: language-specific #SDK implementations of the spec
/*-sdk-contrib: lang-specific provider & hook #implementations
The table in the image shows the mapping between OpenTelemetry feature flag log record conventions and OpenFeature evaluation details fields. Eg. log record attribute 'feature_flag.key' can be mapped to 'flag key'
*22d -> #KubeCon & a bit of #OpenFeature a day #12*
#EvaluationDetails are a flag evaluation's returned data structure. It contains data like the #flagKey, #errorCode, #variant, #reason & #metadata, such as #contextId or #flagSetId. These can be mapped to #OpenTelemetry #log #record conventions.
In the TypeScript code snippet, one can see how an event handler can be added to the OpenFeature client. It shows 2 examples for event type ready and configuration changed.
*25d -> #KubeCon & a bit of #OpenFeature a day #11*
#Events are state changes of the #provider: ready, configuration changed, error, stale
#Event #handlers can be implemented to react to those. Eg. maybe we want to wait until the provider is 'ready' before evaluating feature flags for rendering UI.
🆕 New to OpenFeature? Here’s a great video from @betterstack.com 📚 that gives a full overview: www.youtube.com/watch?v=ZJzQ... #OpenFeature #OpenStandards #FeatureFlagging #ABTesting
The code snippet shows how the OpenFeature client's track function is called passing a tracking event name and TrackingEventDetails, which consist of a numeric value here. In the example, the 'clicked-checkout' event is tracked with a value of 99.77. For server-side applications, the evaluation context parameter can be optionally passed to analyze tracking events in the context of the current user session.
*27d -> #KubeCon & a bit of #OpenFeature a day #10*
Looking at actual #code examples makes it obvious what #tracking calls are used for. Calling the #track function via the #OF #client and passing #TrackingEventDetails a numeric value and other optional data can be sent to the backend:
Join us tomorrow for #YouChoose
This time we’re exploring miscellaneous tools related to IDPs - fun!
We’ll compare #Dapr, #KusionStack, & #OpenFeature with 5-minute presentations from experts, followed by Q&A. Then VOTE on which tool we implement in our demo!

This java code snippet shows how a provider can be implemented to support tracking. It implements the Tracking interface by implementing a track function that returns void. As parameters an event name, an evaluation context and tracking event details can be passed.
*29d -> #KubeCon & a bit of #OpenFeature a day #9*
To support tracking the OpenFeature #provider needs to implement the #Tracking interface, which contains a single function called track. This function performs #side-effects to record the tracking #event (e.g. store a specific metric).
The sequence diagram shows the function calls that are necessary to implement tracking. A tracking hook sends data about flag evaluations coming from the Evaluation API to the Analytics Platform. A separate track call from the Evaluation API to the Analytics Platform stores data about the user session.
*32d -> #KubeCon & a bit of #OpenFeature a day #8*
How does #tracking work?
Calling a #track function stores certain #metrics for a user session (e.g. total purchase amount). #Hooks can be used to store info about #flag #evaluations. Combined, one can see, e.g., how a new feature impacts purchases.
*33 days until #KubeCon & a bit of #OpenFeature a day Nr. 7*
#Experimentation is the term for testing the #impact of a new feature. Certain #metrics of the new feature can be #tracked to, e.g., check if users even like to use the new feature. #Tracking enables product decisions based on #data.
