This Provider is designed to allow the use of OpenFeature with Split, the platform for controlled rollouts, serving features to your users via the Split feature flag to manage your complete customer experience.

This SDK is compatible with Java 11 and higher.

<dependency>
    <groupId>io.split.openfeature</groupId>
    <artifactId>split-openfeature-provider</artifactId>
    <version>1.2.1</version>
</dependency>

Below is a simple example that describes the instantiation of the Split Provider. Please see the OpenFeature Documentation for details on how to use the OpenFeature SDK.

import dev.openfeature.sdk.OpenFeatureAPI;
import io.split.openfeature.SplitProvider;

OpenFeatureAPI api = OpenFeatureAPI.getInstance();
api.setProviderAndWait(new SplitProvider("YOUR_API_KEY"));

If you are more familiar with Split or want access to other initialization options, you can provide a SplitClient to the constructor. See the Split Java SDK Documentation for more information.

import dev.openfeature.sdk.OpenFeatureAPI;
import io.split.openfeature.SplitProvider;
import io.split.client.SplitClient;
import io.split.client.SplitClientConfig;
import io.split.client.SplitFactoryBuilder;

OpenFeatureAPI api = OpenFeatureAPI.getInstance();


SplitClientConfig config = SplitClientConfig.builder()
   .setBlockUntilReadyTimeout(10000)
   .build();
SplitClient splitClient = SplitFactoryBuilder.build("YOUR_API_KEY", config).client();
api.setProviderAndWait(new SplitProvider(splitClient));

After the initial setup you can use OpenFeature according to their documentation.

One important note is that the Split Provider requires a targeting key to be set. Often times this should be set when evaluating the value of a flag by setting an EvaluationContext which contains the targeting key. An example flag evaluation is

Client client = api.getClient("CLIENT_NAME");

EvaluationContext context = new MutableContext("TARGETING_KEY");
Boolean boolValue = client.getBooleanValue("boolFlag", false, context);

If the same targeting key is used repeatedly, the evaluation context may be set at the client level

EvaluationContext context = new MutableContext("TARGETING_KEY");
client.setEvaluationContext(context)

or at the OpenFeatureAPI level

EvaluationContext context = new MutableContext("TARGETING_KEY");
OpenFeatureAPI.getInstance().setEvaluationContext(context)

If the context was set at the client or api level, it is not required to provide it during flag evaluation.

Use the get*Details(...) APIs to get the value and rich context (variant, reason, error code, metadata). This provider includes the Split treatment config as a raw JSON string under flagMetadata["config"]

// boolean/string/number/object all have *Details variants:
FlagEvaluationDetails<String> details =
    client.getStringDetails("my-flag", "fallback", ctx);

String jsonConfig = details.getFlagMetadata().getString("config"); // ← Split treatment config

To use track(eventName, context, details) you must provide:

• targetingKey on the EvaluationContext (non-blank).

• trafficType in the context (string, e.g. "user" or "account").

• A non-blank eventName.

Optional:

• details.value: numeric event value (defaults to 0).

• details.properties: map of attributes (prefer primitives: string/number/boolean/null).

Example:

MutableContext ctx = new MutableContext("user-123");
ctx.add("trafficType", new Value("user"));

TrackingEventDetails details = new MutableTrackingEventDetails(19.99)
    .add("plan", new Value("pro"))
    .add("coupon", new Value("WELCOME10"));

client.track("checkout.completed", ctx, details);
