Thanks for your help.
I'm using 8.0.0. And I found the following code in
`AsyncScanner::ScanBatchesUnorderedAsync`:
```
// If the generator is destroyed before being completely drained, inform
plan
std::shared_ptr<void> stop_producing{
nullptr, [plan, exec_context](...) {
bool not_finished_yet = plan->finished().TryAddCallback(
[&plan, &exec_context] { return [plan, exec_context](const
Status&) {}; });
if (not_finished_yet) {
plan->StopProducing();
}
}};
```
Now I have shared pointers like scanner and recordBatchReader. The possible
cause is that the value of `use_count()` of the shared pointer is greater than
1. The memory cannot be released through `reset()`.
How do I completely destroy the generator mentioned in the above code to
call `stop_producing`?
