java.util.concurrent.CompletionStage<java.util.Optional<java.lang.String>> fetchCachedCustomerGroupId(@Nullable
                                                                                                               java.lang.String key)

Given a key, this method first checks if a cached map of customer group keys -> ids is not empty. If not, it returns a completed future that contains an Optional that contains what this key maps to in the cache. If the cache is empty, the method populates the cache with the mapping of all customer groups' keys to ids in the CTP project, by querying the CTP project customer groups.

After that, the method returns a CompletionStage<Optional<String>> in which the result of its completion could contain an Optional with the id inside of it or an empty Optional if no CustomerGroup was found in the CTP project with this key.

Parameters:

key - the key by which a CustomerGroup id should be fetched from the CTP project.

Returns:

CompletionStage<Optional<String>> in which the result of its completion could contain an Optional with the id inside of it or an empty Optional if no CustomerGroup was found in the CTP project with this key or a blank (null/empty string) key was supplied.
