@lucasbru As @philipnee said, the two mechanisms appear similar and do have overlap. However, not only is it "awkward" to mix them, but it raises correctness questions. `poll()` processes _all_ of the events in the queue from the background thread. However, when the user calls `commit`*, we want to execute only the commit callbacks. As a result, we would have to _filter and remove_ the relevant events from the background thread. The questions that arose: * What if, when processing the commit callbacks, we see error events in the queue? Do we skip them? Execute them? Or something else? * Will removing the events from the background event queue cause unforeseen issues later when calling `poll()`? The answer may be that it's totally fine. We kind of "punted" by doing it this way, not only because of those questions, but because it seemed a bit awkward 🤷♂️ -- This is an automated message from the Apache Git Service.
