How do I notify a process of an SQLite database change done in a different process?

Question

Let\'s say I have two or more processes dealing with an SQLite database - a \"player\" process and many \"editor\" processes.

The \"player\" process reads the database

Answer 1

Edit: I am asuming processes on the same machine.

In my opinion there are two ways:

• Polling (as you mentioned), but keep it to a single value (like a table that just keeps the LastUpdateTime of other tables)

• Use whichever interprocess-communication there is available on the target platform. This could be events in Windows (e.g. in C# (I don't know in Python) the ManualResetEvent, AutoResetEvent, or a Mutex if you want to sacrifice a waiter-thread in each process), or Signals in Linux.
