Review Comment:
> May I ask what safety concern you are referring to?
The `collector.collect(...)` is not a thread-safe method, so if multiple
threads call this method at the same time, the amount of events sent by
`compact_task` will not be equal to the amount of events received by
`Sink:compact_commit`.
