What's the issue?

We have some long running db task that we want to be able to interrupt if needed. When FMDB we have access to sqlite3_interrupt(). I cannot find that for WCDB. Please advise.

No, there is no public interface for sqlite_interrupt.

Will we be getting one in future release?

No, I think.

Here's the bad case. sqlite_interrupt is something about multi-tasking. If the long running task thread happen to begin at the time after sqlite_interrupt but before the transaction of your new task, then sqlite_interrupt can not achieve your purpose. This is a low probability event. However, if something may happen, then it will happen.

You can use WCTCancellationSignal since v2.0.4.
