Why do batch operations send multiple requests?

for the same code, there is no problem to delete it at one time. When the parameter array is deleted in batches and becomes multiple values, more requests will be sent. Is there a back-end problem? There must be no problem with the front end, because a single deletion and batch are the same method.

how can people like us who answer questions help you analyze just by describing you in words? At least give me a pseudo code or something.

if you don't consider anything else, just talk about the number of requests made by the front end, which has nothing to do with the back end.


batch deletion can send an array to the backend


how many requests do you send to the backend?


the frontend sends a request to the backend and my backend only does the receiving operation. Can't you send me this request several times?
confirm the frontend again. Is it possible to change some common things that lead to problems in large-scale batch operations


you send letters and receive letters in the background, you send several letters about the recipient, and the backstage does not pick up the pot.
programmers should not set up flag of 'sure there will be no problem'
