Batch processing or batch erasure - which does 'flushed' mean?

[Mizunanari]

Where is the problem?

https://docs.konghq.com/gateway/latest/kong-plugins/queue/#queue-flush-on-shutdown

What happened?

It is not clear whether flushed means sending the queue request to the upstream server or deleting the queue contents.
I need clarification on the meaning of flashed.

What did you expect to happen?

I expect queue requests to be deleted en masse, is that correct?
