  1. Em có thể lưu dữ liệu tạm ở Local và sau đó save dần dần: tuy nhiên cách này đòi hỏi em phải cứng tay 1 chút trong xử lý I/O cụ thể là làm việc với File, cũng có rủi ro là cái server local có thể bị hết disk.
  2. Em có thể sử dụng kafka, em cứ push dữ liệu và kafka, sau đó ở ở đầu consumer, em sẽ lấy ra dần dần và save vào db: cách này thì đơn giản nhưng lại phát sinh thêm chi phí hạ tầng.
