#load_configurations_to_cache(data) ⇒ Boolean

Load configurations to cache

Delegates to ConfigurationHandler singleton to maintain a single source of truth. This ensures all parts of the application use the same cache.

Parameters:

  • data (Hash) —

    Configuration data with :features, :properties, and :segments keys

Returns:

  • (Boolean) —

    true if configurations were loaded successfully

#process_and_load_configurations(api_response) ⇒ Boolean

Process API response and load to cache

This method:

  1. Takes the raw API response

  2. Calls extract_configurations to parse and validate the data

  3. Calls load_configurations_to_cache to store in cache

Parameters:

  • api_response (Hash) —

    Raw API response data

Returns:

  • (Boolean) —

    true if processing was successful, false otherwise
