What are the databases with hooks?

Question

NoSQL

One feature I really liked about MongoDB was . You can set the lifetime of a document
. I'm interested in the following question: is it possible to somehow subscribe to this deletion and execute some code (for example, send an email notification)? Or maybe there is another database where it can be done?

Answer 1

fresh mongo has Change Streams
https://docs.mongodb.com/manual/changeStreams/
and there are actually a lot of other subds that allow you to subscribe to events from the outside. at least postgress, oracle, ms sql, rethinkdb have some ways.
By the way, for the last two, you can directly subscribe to a change in the selection on request.
for sure, other subds also have something.

Answer 2

In SQL DBMS, this is called triggers.
