        # @option arguments [String] :wait_for_active_shards Set the number of active shards to wait for on the newly created rollover index before the operation returns.
        # @option arguments [Boolean] :lazy If set to true, the rollover action will only mark a data stream to signal that it needs to be rolled over at the next write. Only allowed on data streams.
