Dynatrace OpenFeature Provider for Python

The official Dynatrace OpenFeature provider for Python server-side applications.

Status: Early alpha — not yet ready for production use!

Installation

pip install dynatrace-openfeature-provider-python

Usage

from openfeature import api
from openfeature.evaluation_context import EvaluationContext
from dynatrace.openfeature import DynatraceProvider, DynatraceProviderOptions

options = DynatraceProviderOptions.from_sdk_key(
    'dt01.server_us_<key>.de848e97..._a1b2c3d4e5'
)

api.set_provider(DynatraceProvider(options))
client = api.get_client()

ctx = EvaluationContext(targeting_key='user-123')
enabled = client.get_boolean_value('my-feature', False, ctx)

# On shutdown:
api.shutdown()

Config origin override (labs / dev environments)

By default the config endpoint is derived from the SDK key. To point the provider at a different environment or at an SDK proxy, pass config_origin. The value is an origin only — scheme, host, and optional port, with no path. The provider appends the platform and key segments itself.

api.set_provider(
    DynatraceProvider(sdk_key, config_origin='https://cdn.eu.fm.dynatracelabs.com')
)

Metrics origin override

By default the metrics ingest endpoint is derived from the SDK key. To point metrics at a different environment or an SDK proxy, pass metrics_origin. The value is an origin only: scheme, host, and optional port, with no path. The provider appends /v1/metrics itself.

api.set_provider(
    DynatraceProvider(
        sdk_key,
        metrics_origin='https://metrics.eu.fm.dynatracelabs.com',
    )
)

Architecture

The provider performs in-process flag evaluation using flagd-core. On initialization it fetches a flagd-format JSON config from the Dynatrace CDN and polls for updates every 10 seconds. No external bucketing API is called during evaluation.

State transitions follow providers.md §4.1: NOT_READY → READY → STALE → ERROR, with a 1-minute grace period before STALE → ERROR.
