Issues with data table lookups when running a Telegram bot from a Background Task

How to deal with threading

Using threads on the server is not safe. The server doesn’t know that you are using threads, could kill them (as you found out) and doesn’t work with data tables (see here). You can use threads on your uplink modules, but you might still have problems working with the data tables. You should look at Background Tasks. They are the official way to start a background thread that is data table friendly, doesn’t stop when your request stops, doesn’t timeout and can be monitored or killed by another…

I’m sure you can’t use app_tables from an unofficial thread, and I would be afraid that Anvil would kill that thread whenever it likes.

I don’t know your library, but I always stay away from creating my own threads and try to use callbacks to http endpoints instead. The http endpoint can always use app_tables or start a background task.
