Erik Johnston c72d26c1e1 Refactor EventContext (#12689) ... Refactor how the `EventContext` class works, with the intention of reducing the amount of state we fetch from the DB during event processing. The idea here is to get rid of the cached `current_state_ids` and `prev_state_ids` that live in the `EventContext`, and instead defer straight to the database (and its caching). One change that may have a noticeable effect is that we now no longer prefill the `get_current_state_ids` cache on a state change. However, that query is relatively light, since its just a case of reading a table from the DB (unlike fetching state at an event which is more heavyweight). For deployments with workers this cache isn't even used. Part of #12684		2022-05-10 19:43:13 +00:00
