自从DELETE调用以来X时间之后，如何删除mongodb（mongoose）上的文档？

Question

When I http.delete(api, params, etc..), I don't wanna delete the document immediately, just schedule the deletion after x time depending on a param.

I was thinking to use setTimeout? is that a good way of doing that? what's the proper way to approach this thanks..

Answer 1

if you wanted to delete a document at fix time after insert /update ,you can use a ttl index ,when use ttl index the data will not be delete immediately ,but if the delete time is not fix (may related to your param ) . you can't use the ttl index .

for the scond case . you have to write a applicantion to monitor the collection

compare the data_time delay_time now then delete ,the better is with aggregation .

what is more the setTimeout() is a good way to callback after a certain period of time .
