Description

This operator can be customized into a broad class of aggregate/group/fold operators, based on custom state or timer conditions.

Reactive Streams semantics

emits when the aggregation function decides the aggregate is complete or the timer function returns true

backpressures when downstream backpressures and the aggregate is complete

completes when upstream completes and the last aggregate has been emitted downstream

cancels when downstream cancels
