2 years ago @itssidhere Thanks for the report. Can you provide any logs that shows duration indicating slowness while retrieving the data ? Is it possible for you to debug at native side and see if slowness actually happens while executing the query ? Can you also provide sample document you're querying against and also let us know about the amount of documents in the DB ?

2 years ago @darshankawar If I try to use clearPersistance everything gets back to normal. I think it's mainly because I usually clear the room chats from cloud function and the client side sdk isn't aware of this so it tries to persist every document. The query should be indexed locally just like in Java sdk using setIndexConfig or there should be a parameter in .snapshots() just like in .get() to specify the source of the document cache or server. Please implement setIndexConfig.

Thanks for the feedback. Can you provide an example that shows the actual / current result (ie, slow execution of query) and usage of clearPersistence that helps resolving the issue along with how setIndexConfiguration would help to resolve slow / performance of the query execution ?

2 years ago @darshankawar Any complex query like this
collectionReference
.where('timestamp', isGreaterThan: oneHourAgoTime)
.orderBy('timestamp', descending: true)
.limit(10)
.snapshots()Suppose you start listening to the query and try to add multiple documents (enough to fill up the local cache size). Then simply try to re-attach the listener on the same query you will notice a long delay as this query is not getting locally indexed as it gets on the server side. Clearing the persistence can speed it up again as there is no local cache. Android has an API setIndexConfiguration which sets the index for the local cache( if I am not wrong) to speed up the query locally.
This is my actual usage -
Bloc
Stream<RoomChatState> mapFetchRoomChatEventToState() async* {
try {
yield InitialRoomChatState();
await streamSubscription?.cancel();
streamSubscription = roomChatRepo!.getRoomChat().listen((data) {
roomChats = data;
add(ReceivedRoomChatEvent(roomChat: data)); //it then yields RoomChatReceivedState
});
} catch (exception) {
print(exception);
}
}RoomChatRepo
Stream<List<RoomChat>> getRoomChat() {
CollectionReference collectionReference =
db.collection(PathOf.mohallaChats).doc(mohalla).collection(room);
final now = Timestamp.now().toDate();
final oneHourAgoTime =
Timestamp.fromDate(now.subtract(const Duration(hours: 1)));
return collectionReference
.where('timestamp', isGreaterThan: oneHourAgoTime)
.orderBy('timestamp', descending: true)
.limit(10)
.snapshots()
.transform(StreamTransformer<QuerySnapshot<Map<String, dynamic>>,
List<RoomChat>>.fromHandlers(
handleData: (QuerySnapshot<Map<String, dynamic>> querySnapshot,
EventSink<List<RoomChat>> sink) =>
mapQuerySnapshotToRoomChat(querySnapshot, sink)));
}RoomChatPage
BlocBuilder<RoomChatBloc, RoomChatState>(
bloc: roomChatBloc,
builder: (context, state) {
if (state is RoomChatReceivedState) {
if (showCachedList.value) {
return cachedChatList;
}
cachedChatList =
ImplicitlyAnimatedList<RoomChat>(
reverse: true,
controller: _scrollController,
areItemsTheSame:
(RoomChat a, RoomChat b) =>
a.id == b.id,
items: state.roomChat,
itemBuilder: (context,
Animation<double> animation,
item,
index) {
return FadeTransition(
key: ValueKey(item.id),
opacity: animation,
child: RoomChat()
);
return cachedChatList;
} else {
return RoomChatLoading();
}
},
)To fix the delay I have to call clearPersistance in my main()
Future<void> main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform);
await FirebaseFirestore.instance.clearPersistence();
}As you can see the bloc starts from InitialRoomChatState. After fetching 100s of documents if you re-attach the listeners by calling mapFetchRoomChatEventToState it gets stuck to InitialRoomChatState for a significant amount of time.

2 years ago Thanks for this update. Wondering if you get same behavior without using Bloc ? I am trying to see if the query execution speed behavior is happening without any external dependencies.
itssidhere
commented
2 years ago @darshankawar That is hard to test as we need to populate the cache enough to start noticing the difference. Since it's a production app that is doable but producing a seperate example without any external dependency is hard. Though i am sure about it as clearPersistance fixes the issue so it has something to do with the firestore.

2 years ago I am going ahead and label it for now for team's insights based on above comment. But if you could, a reproducible code sample without third party plugins would be nice to actually narrow down this behavior to the plugin.

2 years ago @itssidhere Are you using Source.cache anywhere? I've noticed that being very slow lately.
itssidhere
commented
2 years ago @larssn No but the plugin implicitly tries to get it from cache first so that's why it's the same thing. Cache is very slow and disabling it is the only option.

2 years ago I am also experiencing this same issue too from android. Here is my experience...
When the user install the app, everything is normal and the queries are very fast for both Source.cache and Source.server. Then after using the app for a while, all queries becomes extremely slow for both Source.cache and Source.server and the more the user keeps using the app, the slower it becomes. The problem persist even after the user manually clears the cache.
The queries only becomes faster again after the user uninstall the app then reinstall it. But as they keep using the app, the queries becomes slower and slower with time.
Things I have tried:
None of this has helped, I only have to uninstall the app and reinstall for the queries to be fast again, but becomes slower and slower with time.

2 years ago @Peirazo True. @darshankawar Can you please look into this issue.

2 years ago This issue is also discussed in the recent firebase video. But Android has a solution for this. Please implement the same in flutter.

Sample project
Additional context
I am experiencing an issue. When the user has subscribed to this query for a long and has retrieved multiple documents. This query becomes slow over time as reported in my production app. The user has to clear their app's cache. Can you please tell me how should I proceed with this? I want this query to fetch documents from the server and not the local cache in order to avoid this issue but still want persistence enabled in my app. I looked up on the internet and found a method to create a local index for a java client.
