Simultaneous writing to Mongu?

Question

MongoDB

It is possible that a separate record will be retrieved from the database and updatenut at the same time. That is, as a result, what will be updated last will be preserved. Is it possible to somehow avoid this?

Answer 1

Well, if at first it is "gotten", and after 0.0005 seconds the "update" and the "gotten" will no longer be relevant - does it bother you?
It's not clear what you want.
Monga has a bunch of concepts to solve problems like this.
For example, findAndModify or Read Isolation.
However, it is not clear exactly what you want...
