Class FeatureFetchRetryPolicy

java.lang.Object

growthbook.sdk.java.retry.FeatureFetchRetryPolicy

public class FeatureFetchRetryPolicy
extends Object

Configures bounded exponential backoff for feature fetch requests.

The default policy allows five total attempts. Delays are calculated before each retry, so the default five attempts produce retry waits of 1s, 2s, 4s, and 8s. The 16s default maximum delay caps custom policies with more attempts.
