Hi Luis, You cannot have event-time early firings on both chained window operators. The reason is that each early result from the first window operator will have a timestamp equal to window.maxTimestamp-1. So in the second windowing operator, they will be buffered until the watermark signaling the end of the window arrives.
Now for the second point, I think that what you have understood is correct. The "ctx.registerEventTimeTimer(window.getEnd())” registers a timer to call the onEventTime().
