Datastore save operations incomplete when series of writes happens
Description
I have a code such that it writes records to different tables one after the other. I have been struggling with an issue where some of the writes don't show up in a DDB table and they also don't throw any errors. When I add breakpoints and execute the code line by line, they all work properly.
Code looks something like this.
...
await tableOneRepo.save(infoOne);
.
.
await tableTwoRepo.save(infoTwo);
.
.
await tableThreeRepo.save(infoThree);
.
.
await tableFourRepo.save(infoThree);
...
I tried running the app from Xcode, and I saw an error message like this. AppBadgeCount is the table that continues to fail to insert the record.
2022-09-23 23:31:39.136612+0900 Runner[95535:5375337] flutter: DataStoreException(message: Received a create mutation for an item that has already been created, recoverySuggestion: Review your app code and ensure you are not issuing incorrect DataStore.save() calls for the same model.

When I try to add a record to this table only, it works fine. I'm wondering if there is any throttling taking in place. I'm currently writing to about 10 tables in a row.
I have automerge enabled.

Hello @skim037 - Can you let me know what type tableThreeRepo/tableFourRepo is, and/or the code for the save method on these types?
The table is really simple.
type AppBadgeCount @model @auth(rules: [{allow: public}]) {
id: ID!
profile_id: ID! @primaryKey
count: Int
}
Future<void> save(AppBadgeCount appBadgeCount) async {
await Amplify.DataStore.save(appBadgeCount);
}
I tried two thing. First, I moved the call to save appBadgeCount to the start of the method (before series of other save operations), and it was saved properly. Second, I tried without the primaryKey annotation (save operation happens after series of other save operations), and it also worked properly. But when the table has primaryKey annotation and save call happens after series of other save calls in the same function, it fails to save a record to the table.
Another call that fails to sync to the backend is updating a profile table. A profile record was created properly from another method, and when I try to updated it, it doesn't work. Below is a record that was created by other calls. It was created and updated properly. But when I tried to update it after series of other writes in the same function, update request doesn't get synced to the backend (no exception is thrown).

Profile table
type Profile @model @auth(rules: [{allow: public}]) {
id: ID!
profile_username: String! @index(name: "byUsername", queryField: "byUsername")
email: String! @index(name: "byEmail")

profile_interests: [ProfileInterest] @hasMany
verification: Verification @hasOne
searchableProperties: SearchableProperties @hasOne
filter: Filter @hasOne
advancedFilter: AdvancedFilter @hasOne
}
//Call to update the profile table.
Profile updatedProfile = sessionBloc.profile!.copyWith(
profile_status: ProfileStatus.STANDARD,
profileMoreInfoId: moreInfo.id,
profileVerificationId: verification.id,
profileFilterId: filter.id,
profileAdvancedFilterId: advancedFilter.id,
moreInfo: moreInfo,
verification: verification,
filter: filter,
advancedFilter: advancedFilter,
);
await profileRepo.save(updatedProfile);
And as I mentioned earlier, these calls succeeds when I add a breakpoint and execute line by line.
I tried running it from Xcode. And I see a log saying model is saved successfully.
Successfully saved model: FlutterSerializedModel(values: ["profile_username": Amplify.JSONValue.string("aaaa"), "profileSearchablePropertiesId": Amplify.JSONValue.null, "createdAt": Amplify.JSONValue.null, "profileFilterId": Amplify.JSONValue.null, "profile_status": Amplify.JSONValue.string("STANDARD"), "profileMoreInfoId": Amplify.JSONValue.null, "profileUsernameId": Amplify.JSONValue.string("d136aff5-bbf7-462a-ae81-88cbea6d45b6"), "birthday": Amplify.JSONValue.string("2000-01-01"), "id": Amplify.JSONValue.string("84ec0f9e-c6b7-4446-9cdf-24dec57228ea"), "profileAdvancedFilterId": Amplify.JSONValue.null, "main_photo": Amplify.JSONValue.null, "profileBasicInfoId": Amplify.JSONValue.string("861117e7-5052-4cba-9311-0a9b1b0ae8b8"), "updatedAt": Amplify.JSONValue.null, "school": Amplify.JSONValue.string("school"), "introduction": Amplify.JSONValue.string("hi"), "userID": Amplify.JSONValue.string("377314b3-d9e0-4474-bd6d-915b6b2ec5c8"), "email": Amplify.JSONValue.string("[email protected]"), "gender": Amplify.JSONValue.string("MAN"), "profileAppBadgeCountId": Amplify.JSONValue.null, "__typename": Amplify.JSONValue.string("Profile"), "profileVerificationId": Amplify.JSONValue.null, "work": Amplify.JSONValue.string("work")], _modelName: "Profile")
However, I do not see new property "profile_status: STANDARD" in DDB.
I have another datapoint that might be useful. I hope you can reproduce this and see what's going on.
I created three new tables.
type TestTableOne @model @auth(rules: [{allow: public}]) {
id: ID!
profile_id: ID! @primaryKey
count: Int
}
type TestTableTwo @model @auth(rules: [{allow: public}]) {
id: ID!
profile_id: ID! @primaryKey
count: Int
}
type TestTableThree @model @auth(rules: [{allow: public}]) {
id: ID!
profile_id: ID! @primaryKey
count: Int
}
Then I execute save operation with the same profile Id.
final profileId = UUID.getUUID();
final testTableOne = TestTableOne(profile_id: profileId, count: 100);
await appBadgeCountRepo.saveTestOne(testTableOne);
final testTableTwo = TestTableTwo(profile_id: profileId, count: 100);
await appBadgeCountRepo.saveTestTwo(testTableTwo);
final testTableThree = TestTableThree(profile_id: profileId, count: 100);
await appBadgeCountRepo.saveTestThree(testTableThree);
I checked DDB table, and I see this record in table one and two, but not in table three. I think the order matters here. For example, if I execute two, three and one, table two and three has a record but one doesn't.
I believe this test demonstrates the issue I'm currently facing. Please let me know if I'm doing something wrong here. Thanks.
The table is really simple.
Hi @skim037 - I am actually looking for the code for tableThreeRepo and tableFourRepo. It is not clear to me why you are calling save on the same model twice. If I can see the code for that save method, it may make more sense.
save operations all look like this.
Future<void> saveTestOne(TestTableOne testTableOne) async {
await Amplify.DataStore.save(testTableOne);
}
Future<void> saveTestTableTwo(TestTableTwo testTableTwo) async {
await Amplify.DataStore.save(testTableTwo);
}
Future<void> saveTestThree(TestTableThree testTableThree) async {
await Amplify.DataStore.save(testTableThree);
}
It seems like the issue happens when there is a series of writes (different models) that uses same custom primary key which was the point I was trying to get across with the previous comment.
Your original code snippet included saving the same model twice. infoThree was passed into tableThreeRepo.save and tableFourRepo.save. Was that intentional? If so, what is the use case for saving the same model twice in a row?
await tableThreeRepo.save(infoThree);
.
.
await tableFourRepo.save(infoThree);
No it's by mistake. They should be different model. Please disregard my original code snippet and look at the my latest replies.
Hi @skim037 in your code it looks like you're using the same id: "profileId" to save 3 different items. Can you try giving a different id for each testTable you create?
final profileId = UUID.getUUID();
final testTableOne = TestTableOne(profile_id: profileId, count: 100);
await appBadgeCountRepo.saveTestOne(testTableOne);
final testTableTwo = TestTableTwo(profile_id: profileId, count: 100);
await appBadgeCountRepo.saveTestTwo(testTableTwo);
final testTableThree = TestTableThree(profile_id: profileId, count: 100);
await appBadgeCountRepo.saveTestThree(testTableThree);
final profileIdOne = UUID.getUUID();
final profileIdTwo = UUID.getUUID();
final profileIdThree = UUID.getUUID();
final testTableOne = TestTableOne(profile_id: profileIdOne, count: 106);
await appBadgeCountRepo.saveTestOne(testTableOne);
final testTableTwo = TestTableTwo(profile_id: profileIdTwo, count: 106);
await appBadgeCountRepo.saveTestTwo(testTableTwo);
final testTableThree = TestTableThree(profile_id: profileIdThree, count: 106);
await appBadgeCountRepo.saveTestThree(testTableThree);
Above code works as expected. I see new records in all three tables. But this is not what I want. I'm using profieId as a custom primary key and I'm trying to save records with a same profile Id.
And as I mentioned earlier, using a same profile Id works if I add a breakpoint and step through the code line by line.
This should be pretty easy to try to reproduce. Are you not seeing the same behavior?
Hi @skim037 - I was not able to reproduce this by saving many updates to the same model in succession. Below is the code I am using to attempt a reproduction. If you are still experiencing this, could you provide a minimal reproduction of the issue (similar to the snippet below) so that we can reproduce this?
final blog = Blog(name: 'My blog 123');
await Amplify.DataStore.save(blog);
await Amplify.DataStore.save(
blog.copyWith(name: 'My blog 1234'),
);
await Amplify.DataStore.save(
blog.copyWith(name: 'My blog 1235'),
);
await Amplify.DataStore.save(
blog.copyWith(name: 'My blog 1236'),
);
await Amplify.DataStore.save(
blog.copyWith(name: 'My blog 1237'),
);
await Amplify.DataStore.save(
blog.copyWith(name: 'My blog 1238'),
