Update of 5.6 to 5.7.1 causes lots of Timeout in include queries

[JohnStrim]

SUMMARY

Update to this version has produced many Timeouts in EF Core

DETAILS

In our logic we are extensively using query strings for filtering, including relationships and paging which in previous versions used to perform very well (Generally under 1 sec).
When updating to version 5.7.1 we started having a lot of Timeout in Db Queries. To provide more context we were trying to include relationships that are 2 or 3 level deep from our original resource: (ex. include=products.unitGroup,products.unitGroup.units)
Also we noticed a big delay even in simple GET queries which used to return result under 200ms and now performance has up to 600ms with no appart explanation.
We've tried to do an EF Performance Update: (Include the UseQuerySplittingBehavior(QuerySplittingBehavior.SplitQuery)) but this seems to causes many Data is Null Exceptions when including relationships.
Is there any suggestions as far as configuration or minimum versions that we should be aware of to avoid this overhead?

VERSIONS USED

• JsonApiDotNetCore version: 5.7.1
• ASP.NET Core version: 8.0
• Entity Framework Core version: 8.0.1, 9.0.5 (Tried Both)
• Database provider: SQL Server

Let me provide some more Context.
Here are the logs of a GET Call with a complex query string (I've removed double Log Messages that for some reason I'm getting, sensitive query data and the actual log of the db query because of data sensitivity but left the execution times:

Please Notice that even EF Core has now provided new warnings after the update and If I were to show you the full query you could see that it trippled in its size... Since there is no EF Core update that our team did can you help us explain this?

[bkoelman]

Are you using resource inheritance? It would help to share the before/after SQL for the request URL.

[JohnStrim]

Yes we are. products is a base resource with 5 or 6 children Resources

That looks awful :)

Possibly caused by #1641. Can you try turning off pagination in options and see if that helps?

Another thing to inspect (with pagination enabled) would be to compare QueryLayer.ToString() in EntityFrameworkCoreRepository.ApplyQueryLayer. Unfortunately, we don't log that yet, so it requires building from source.

[JohnStrim]

@bkoelman Tried to apply your idea of turning off Pagination by setting DefaultPageSize = null, which wouldn't apply much in our scenarios since we are using this api to fill client Datagrids that use pagination. The change did affect the query but the end result is the same, in other words still produces a Timeout...
Here are the logs:

Also here is the QueryLayer.ToString() when pagination is not set to null but also is not specifically set in the query string. It appears to be correct in my opinion and similar to logs we were originally getting and we sent in previous messages

QueryLayer<PriceGroup>
{
  Filter: and(any(id,'29BB1DED-4887-43B7-84B2-94769721EDBD','49413E3E-91D4-4709-8062-6D68CB9F4961','7BB75DA4-14AC-44BF-923B-DF513A9505BF','C0C52261-2BF6-4650-A96B-B252A9239D8E','DA794453-BE10-4B63-94F6-4654B4C14DA9'),equals(isDeleted,'false'))
}

@bkoelman since it appears to be a bug of 5.7.0 and 5.7.1 versions may I suggest turning this issue into a bug and handling it this was? We have paused our version update until this is resolved. Please let us know if we can provide any further insight or assistance on resolving this since this is block us as well.

[bkoelman]

I'm surprised by that query layer (assuming it originates from JADNC v5.7.1). I would have expected to see multiple field selectors (one per derived type), with pagination inside them. But it also has no includes, so it doesn't seem to represent the original problematic request with both a filter and includes. The initial log file contains "HTTP GET /v1/priceGroups", which doesn't have query string parameters, but they may have been trimmed off in logs for redaction.

Can you confirm that the QueryLayer originates from the request URL /v1/priceGroupsfilter=and(any(id,'XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX','XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX','XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX',XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX','XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX'),equals(isDeleted,'false'))&include=products.unitGroup.units using JADNC v5.7.1? If not, please provide the appropriate one.

I don't know yet whether this is a bug or intended behavior. That doesn't mean I won't try to help you, but I need to understand the root cause first. Based on that, maybe JADNC can provide extra configuration settings to prevent this from happening, assuming the query becomes too complex for SQL Server to handle. But I'm just guessing now.

It's hard for me to track what's happening, ie. I don't know the data model and its inheritance hierarchy. Would it be possible to create a minimal repro that I can debug, in the form of a git repo? Then I can analyze the query layer, the resulting LINQ expression, and its SQL, and compare those with the old version of JADNC. I also wonder if the problem is specific to SQL Server. Seeding the minimal repro with sample data should be easy with Bogus Faker, which we already use for integration tests.

Please Notice that even EF Core has now provided new warnings after the update and If I were to show you the full query you could see that it trippled in its size...

Based on the conversations at dotnet/efcore#29182 and dotnet/efcore#29665, this warning may not be appropriate; the "solution" to activate query splitting may actually make the situation worse. I recommend ignoring this warning while trying to identify the root cause of the problem.
