How to process large Response Body? (log-util.lua)

[Git4Future]

apisix/apisix/utils/log-util.lua

    if log_response_body then
        local final_body = core.response.hold_body_chunk(ctx, true)
        if not final_body then
            return
        end
        ctx.resp_body = final_body
    end

If the fina_body here is a super-large response body,just like a download file request,can i limit the body size to do collect action ?
