This setting may be useful if you use JournalMode set to JournalMode.Persist or Locking set to LockingMode.Exclusive. In these cases the rollback journal file may remain in the file-system after committing a transaction. If it is larger than the specified value after committing a transaction, it is truncated.
Negative values mean no limit. The default value is -1.
This property uses the corresponding SQLite PRAGMA - journal_size_limit.
