I don't known whether it's a typo as the arrow I point ? I think it is subscriber and not publisher need to be handled，it is right ?

It's correct there is not typo error.

@amitshekhariitbhu I am sorry ，it's my fault to understand . It's right , the items emitted by publisher is overflow , and the subscriber is too tired and too slow to handle these items.
