Overview

Configuration options related to Big Segments.

Big Segments are a specific type of segments. For more information, read the LaunchDarkly documentation: docs.launchdarkly.com/home/users/big-segments

If your application uses Big Segments, you will need to create a ‘BigSegmentsConfig` that at a minimum specifies what database integration to use, and then pass the `BigSegmentsConfig` object as the `big_segments` parameter when creating a Config.

Examples:

Configuring Big Segments with Redis

store = LaunchDarkly::Integrations::Redis::new_big_segments_store(redis_url: "redis://my-server")
config = LaunchDarkly::Config.new(big_segments:
  LaunchDarkly::BigSegmentsConfig.new(store: store))
client = LaunchDarkly::LDClient.new(my_sdk_key, config)
