Optimal SQLite settings for Django (via) Giovanni Collazo put the work in to figure out settings to make SQLite work well for production Django workloads. WAL mode and a busy_timeout of 5000 make sense, but the most interesting recommendation here is "transaction_mode": "IMMEDIATE" to avoid locking errors when a transaction is upgraded to a write transaction.

Giovanni's configuration depends on the new "init_command" support for SQLite PRAGMA options introduced in Django 5.1alpha.
