Sqlite update hook with external database

Question

Basically i'm developing an application in python where it listens to external sqlite database changes, so far i implemented update_hook()(from this example: SQLite Data Change Notification Callbacks in Python or Bash or CLI) it worked well when i launch SQL statements in the same process however when i use external database that has now relation with my process it doesn't work. My question is how do i listen to database changes from an external process(A) that has no relation with process(B).

Answer 1

SQLite has no mechanism by which another process can be notified.

You have to implement some communication mechanism outside of SQLite.
