Pre-release

This release is a pre-release and may not be stable for production use.

Statsig helps you move faster with feature gates (feature flags), and/or dynamic configs. It also allows you to run A/B/n tests to validate your new features and understand their impact on your KPIs. If you're new to Statsig, check out our product and create an account at statsig.com.

Getting Started

Read through the Documentation or check out the Samples.

ID-list file routing and fallback

download_id_list_file_api selects the preferred base URL for file downloads. Enable fallback_to_statsig_api to try the original file URL from the manifest after an overridden request exhausts its retries, provided that URL belongs to the trusted HTTPS OpenAI CDN origin:

let options = statsig_rust::StatsigOptions {
    download_id_list_file_api: Some("http://statsig-proxy:8080".to_string()),
    fallback_to_statsig_api: Some(true),
    ..Default::default()
};

Fallback accepts only https://statsigcdn.openai.com with the default port or explicit :443. Fallback sends no request or SDK credentials to other manifest origins; the original request error is returned. Fallback does not follow redirects. Custom network providers must implement send_without_redirects; otherwise the fallback returns an error without sending a request. Fallback preserves the URL's path and query, the file identity, and the byte offset for incremental updates. Each destination uses its own range protocol: a range query for the OpenAI CDN, or Range and statsig-id-list-file-size headers for other hosts.

Set fallback_to_statsig_api to Some(false) or leave it unset to keep file downloads strictly on the selected destination. There is no second attempt when the override resolves to the original URL, no override is set, or the request fails with an authentication rejection (401/403) or another non-retryable error. Response parsing failures do not trigger fallback. This uses the existing option across language bindings; wrappers that disable it continue to opt out.

A successful proxy request makes no additional request. An eligible failure can add one request to the trusted CDN URL using the existing network timeout and retry policy. The next synchronization starts with the configured override again.

Read-only data stores

Rust data stores can override DataStoreTrait::is_read_only(); Python DataStore subclasses can override the synchronous is_read_only() method:

def is_read_only(self) -> bool:
    return not self.is_leader

The default is False, preserving existing writable stores. Return True for a follower that only consumes shared cache entries. Bootstrap/polling reads and config hydration/evaluation remain enabled, but full network responses no longer build or compress hydrated cache snapshots or call the datastore's write methods. Delta responses continue to skip snapshot writes. Keep the role stable during an update. A failing Python capability check is treated as read-only.
