Overview

Builder for a polling data source that communicates with LaunchDarkly’s FDv2 polling endpoint.

This builder can be used with ConfigBuilder#initializers or ConfigBuilder#synchronizers to create custom data system configurations.

The polling data source periodically fetches data from LaunchDarkly. It supports conditional requests via ETags, so subsequent polls after the initial request only transfer data if changes have occurred.

Example

polling = LaunchDarkly::DataSystem.polling_ds_builder
  .poll_interval(60)
  .base_uri("https://custom-endpoint.example.com")

data_system = LaunchDarkly::DataSystem.custom
  .synchronizers([polling])

Instance Method Details

#build(sdk_key, config) ⇒ LaunchDarkly::Impl::DataSystem::PollingDataSource

Builds the polling data source with the configured parameters.

This method is called internally by the SDK. You do not need to call it directly; instead, pass the builder to ConfigBuilder#initializers or ConfigBuilder#synchronizers.

Parameters:

Returns:

def build(sdk_key, config)
  http_opts = build_http_config
  requester = @requester || LaunchDarkly::Impl::DataSystem::HTTPPollingRequester.new(sdk_key, http_opts, config)
  LaunchDarkly::Impl::DataSystem::PollingDataSource.new(@poll_interval || DEFAULT_POLL_INTERVAL, requester, config.logger)
end

#poll_interval(secs) ⇒ PollingDataSourceBuilder

Sets the polling interval in seconds.

This controls how frequently the SDK polls LaunchDarkly for updates. Lower values mean more frequent updates but higher network traffic. The default is DEFAULT_POLL_INTERVAL seconds.

Parameters:

  • secs (Float) —

    Polling interval in seconds

Returns:

  self
end

#requester(requester) ⇒ PollingDataSourceBuilder

Sets a custom Requester for this polling data source.

By default, the builder uses an HTTP requester that communicates with LaunchDarkly’s FDv2 polling endpoint. Use this method to provide a custom requester implementation for testing or non-standard environments.

Parameters:

Returns:
