// how to get the first/last x events for a room?
|
||
|
|
// we don't want to specify the sort key, but would need an index for the room_id?
|
||
|
|
// take sort_key as primary key then and have index on event_id?
|
||
|
|
// still, you also can't have a PK of [room_id, sort_key] and get the last or first events with just the room_id? the only thing that changes it that the PK will provide an inherent sorting that you inherit in an index that only has room_id as keyPath??? There must be a better way, need to write a prototype test for this.
|

|
|
// SOLUTION: with numeric keys, you can just us a min/max value to get first/last
|
||
|
|
// db.createObjectStore("members", ["room_id", "state_key"]);

const state = db.createObjectStore("roomState", ["event.room_id", "event.type", "event.state_key"]);
