### Motivation <strong>Background-1</strong>: After all consumers are removed, the Dispatcher will call `cursor.rewind` and reset all attributes in memory, making the Dispatcher like a new Dispatcher. <strong>Background-2</strong>: there have a variable `recentlyJoinedConsumers` records the read position of the cursor when a new consumer registers. If there has an in-flight reading, Dispatcher does not call `cursor.rewind` immediately but waits for the in-flight reading complete, it makes the `recentJoinedPosition` of new consumers in the wrong position. ### Modifications After `rewind`, clear `recentJoinedPosition` ### Documentation <!-- DO NOT REMOVE THIS SECTION.
