Question about subscription results including or excluding event at specified commit position

johnbywater opened this issue · comments

@ylorph, as requested here's a GH Issue to discuss the inclusive/exclusive behaviour of EventStoreDB for subscriptions from a specific commit position. As we saw, catch up subscriptions seem to be definitely exclusive, but persistent subscriptions less than definitely exclusive. I will post a link to the test for this shortly...

Setting the filter option seems to have stabilised this behaviour, so that: persistent subscriptions are definitely inclusive and catch-up subscriptions are definitely exclusive of a specified commit position in the events that are returned in the responses.
