immediate
Transaction Mode: Immediate
Applies IMMEDIATE
mode to this transaction; another transaction object is returned (a copy), applying this mode, but with the same properties otherwise.
SQLite documentation describes IMMEDIATE
-mode transactions as:
"IMMEDIATE
causes the database connection to start a new write immediately, without waiting for a write statement. The BEGIN IMMEDIATE
might fail with SQLITE_BUSY
if another write transaction is already active on another database connection."
