# EF Core Query Translation Fix
|
||||
|
||||
## Issue
|
||||
|
||||
The application was encountering `System.InvalidOperationException` at runtime when accessing multiple API endpoints. EF Core 11 with PostgreSQL could not translate complex LINQ queries that combined:
|
||||
|
||||
1. **DistinctBy operations** with **Include (eager loading)** of navigation properties
|
||||
2. **Nested subqueries** with Min() operations referencing the same subquery
|
||||
3. **Count operations** after applying DistinctBy
|
||||
4. **Complex joins** with DistinctBy in the expression tree
|
||||
|
||||
### Affected API Endpoints
|
||||
|
||||
The following endpoints were throwing `InvalidOperationException` with message "The LINQ expression ... could not be translated":
|
||||
|
||||
1. **`GET /Items/Filters`** - Query filters endpoint (FilterController.GetQueryFiltersLegacy)
|
||||
2. **`GET /Studios`** - Studios list endpoint
|
||||
3. **`GET /Items`** - Items query endpoint (ItemsController.GetItems)
|
||||
4. **`GET /Users/{userId}/Items/Latest`** - Latest items endpoint
|
||||
|
||||
### Error Locations
|
||||
|
||||
**Initial Discovery:**
|
||||
- **Line 496**: `GetItemListAsync` - DistinctBy combined with ApplyGroupingFilter
|
||||
- **Line 582**: `GetLatestItemListAsync` - DistinctBy combined with ApplyGroupingFilter
|
||||
|
||||
**Additional Errors Found During Testing:**
|
||||
- **Line 400**: `GetItemsAsync` - CountAsync() after applying DistinctBy via ApplyGroupingFilter
|
||||
- **Line 1822**: `GetItemValues` - DistinctBy in complex LINQ expression with joins
|
||||
- **Line 578**: `GetLatestItemListAsync` (with limit path) - ApplyGroupingFilter adds untranslatable DistinctBy
|
||||
- **Line 619**: `GetLatestItemListAsync` (without limit path) - Same issue
|
||||
|
||||
### Root Cause
|
||||
|
||||
EF Core has limitations when translating complex LINQ expressions:
|
||||
- **DistinctBy + Include**: When you apply `DistinctBy()` and then load related entities with `.Include()`, EF Core must translate this into a single SQL query, which can fail
|
||||
- **ApplyGroupingFilter Method**: This helper method adds `DistinctBy()` to IQueryable, which cannot be translated even when only selecting IDs afterwards
|
||||
- **DistinctBy in Expression Tree**: Once `DistinctBy` is in the query expression tree, it remains untranslatable regardless of subsequent operations
|
||||
|
||||
## Solution
|
||||
|
||||
### 1. GetItemListAsync Fix
|
||||
|
||||
**Problem:**
|
||||
This method had TWO code paths (random sort and non-random sort) that both called `ApplyGroupingFilter`, which applies `DistinctBy()` to the IQueryable. Even when only selecting IDs afterwards, EF Core cannot translate the `DistinctBy` in the expression tree.
|
||||
|
||||
**Initial Fix Attempt (Incomplete):**
|
||||
```csharp
|
||||
// This still failed because ApplyGroupingFilter adds DistinctBy to the query
|
||||
dbQuery = ApplyGroupingFilter(context, dbQuery, filter); // DistinctBy added here
|
||||
dbQuery = ApplyQueryPaging(dbQuery, filter);
|
||||
|
||||
// Even though we only select IDs, DistinctBy is still in the expression tree
|
||||
var itemIds = await dbQuery
|
||||
.Select(e => e.Id)
|
||||
.ToListAsync(cancellationToken); // Translation fails!
|
||||
```
|
||||
|
||||
**Final Fix (Working):**
|
||||
```csharp
|
||||
// Apply ordering first (no DistinctBy yet)
|
||||
dbQuery = ApplyOrder(dbQuery, filter, context);
|
||||
|
||||
// Load IDs + keys to memory WITHOUT calling ApplyGroupingFilter
|
||||
var itemsWithKeys = await dbQuery
|
||||
.Select(e => new
|
||||
{
|
||||
e.Id,
|
||||
e.PresentationUniqueKey,
|
||||
e.SeriesPresentationUniqueKey
|
||||
})
|
||||
.ToListAsync(cancellationToken);
|
||||
|
||||
// Apply grouping in-memory using reflection-based helper
|
||||
var groupedIds = ApplyGroupingInMemory(itemsWithKeys, filter);
|
||||
|
||||
// Apply paging to ID list
|
||||
var pagedIds = ApplyPagingToIds(groupedIds, filter);
|
||||
|
||||
// Load full entities with navigations
|
||||
var results = await ApplyNavigations(context.BaseItems.Where(e => pagedIds.Contains(e.Id)), filter)
|
||||
.ToListAsync(cancellationToken);
|
||||
|
||||
// For random sort, maintain the order from pagedIds
|
||||
if (hasRandomSort)
|
||||
{
|
||||
var itemsById = results.ToDictionary(i => i.Id);
|
||||
return pagedIds.Select(id => itemsById[id]).ToArray();
|
||||
}
|
||||
```
|
||||
|
||||
**Why It Works:**
|
||||
- Ordering happens server-side (can be translated)
|
||||
- Only IDs and grouping keys are loaded to memory (small dataset)
|
||||
- `DistinctBy` equivalent happens in-memory via `ApplyGroupingInMemory` using reflection
|
||||
- Full entities loaded in separate, simple query by ID
|
||||
- Random sort order is preserved by using the ID list order
|
||||
|
||||
**Original Code (Before):**
|
||||
```csharp
|
||||
dbQuery = ApplyGroupingFilter(context, dbQuery, filter); // Applies DistinctBy
|
||||
dbQuery = ApplyQueryPaging(dbQuery, filter);
|
||||
|
||||
// Get IDs first, then load full entities with navigations
|
||||
var itemIds = await dbQuery
|
||||
.Select(e => e.Id)
|
||||
.ToListAsync(cancellationToken); // Translation fails here
|
||||
|
||||
var results = await ApplyNavigations(context.BaseItems.Where(e => itemIds.Contains(e.Id)), filter)
|
||||
.ToListAsync(cancellationToken);
|
||||
```
|
||||
|
||||
### 2. GetLatestItemListAsync Fix
|
||||
|
||||
**Problem:**
|
||||
This method has **TWO code paths** (with limit and without limit) that BOTH call `ApplyGroupingFilter`, which applies `DistinctBy()` to the IQueryable. Even when loading IDs first, EF Core cannot translate the `DistinctBy` because it's already in the expression tree.
|
||||
|
||||
**Before (Both Paths Had Same Issue):**
|
||||
```csharp
|
||||
// Path 1: With limit
|
||||
var minDateThreshold = limitedResults.Min(s => s.MaxDateCreated);
|
||||
filter.Limit = null;
|
||||
|
||||
var mainquery = PrepareItemQuery(context, filter);
|
||||
mainquery = TranslateQuery(mainquery, context, filter);
|
||||
mainquery = mainquery.Where(g => g.DateCreated >= minDateThreshold);
|
||||
mainquery = ApplyGroupingFilter(context, mainquery, filter); // Applies DistinctBy
|
||||
mainquery = ApplyQueryPaging(mainquery, filter);
|
||||
|
||||
// Get IDs first to avoid DistinctBy + Include translation errors
|
||||
var itemIds = await mainquery
|
||||
.Select(e => e.Id)
|
||||
.ToListAsync(cancellationToken); // Translation fails!
|
||||
|
||||
// Path 2: Without limit - SAME ISSUE
|
||||
var minDateThreshold = groupedResults.Min(s => s.MaxDateCreated);
|
||||
filter.Limit = null;
|
||||
|
||||
var mainquery = PrepareItemQuery(context, filter);
|
||||
mainquery = TranslateQuery(mainquery, context, filter);
|
||||
mainquery = mainquery.Where(g => g.DateCreated >= minDateThreshold);
|
||||
mainquery = ApplyGroupingFilter(context, mainquery, filter); // Applies DistinctBy
|
||||
mainquery = ApplyQueryPaging(mainquery, filter);
|
||||
|
||||
var itemIds = await mainquery
|
||||
.Select(e => e.Id)
|
||||
.ToListAsync(cancellationToken); // Translation fails!
|
||||
```
|
||||
|
||||
**After (Both Paths Fixed):**
|
||||
```csharp
|
||||
// Path 1: With limit
|
||||
var minDateThreshold = limitedResults.Min(s => s.MaxDateCreated);
|
||||
filter.Limit = null;
|
||||
|
||||
var mainquery = PrepareItemQuery(context, filter);
|
||||
mainquery = TranslateQuery(mainquery, context, filter);
|
||||
mainquery = mainquery.Where(g => g.DateCreated >= minDateThreshold);
|
||||
|
||||
// Apply ordering first (before loading to memory)
|
||||
mainquery = ApplyOrder(mainquery, filter, context);
|
||||
|
||||
// Get IDs + keys to memory (without DistinctBy in the query)
|
||||
var itemsWithKeys = await mainquery
|
||||
.Select(e => new { e.Id, e.PresentationUniqueKey, e.SeriesPresentationUniqueKey })
|
||||
.ToListAsync(cancellationToken);
|
||||
|
||||
if (itemsWithKeys.Count == 0)
|
||||
{
|
||||
return Array.Empty<BaseItem>();
|
||||
}
|
||||
|
||||
// Apply grouping in-memory (client-side evaluation)
|
||||
var groupedIds = ApplyGroupingInMemory(itemsWithKeys, filter);
|
||||
|
||||
// Apply paging to IDs
|
||||
var pagedIds = ApplyPagingToIds(groupedIds, filter);
|
||||
|
||||
if (pagedIds.Count == 0)
|
||||
{
|
||||
return Array.Empty<BaseItem>();
|
||||
}
|
||||
|
||||
// Load full entities with navigations
|
||||
var results = await ApplyNavigations(context.BaseItems.Where(e => pagedIds.Contains(e.Id)), filter)
|
||||
.ToListAsync(cancellationToken);
|
||||
|
||||
return results
|
||||
.Where(e => e is not null)
|
||||
.Select(w => DeserializeBaseItem(w, filter.SkipDeserialization))
|
||||
.Where(dto => dto is not null)
|
||||
.ToArray()!;
|
||||
|
||||
// Path 2: Without limit - SAME FIX APPLIED
|
||||
```
|
||||
|
||||
**Why It Works:**
|
||||
- **ApplyGroupingFilter is never called** - Avoids adding DistinctBy to the query
|
||||
- Ordering happens server-side before loading to memory
|
||||
- Only IDs and grouping keys are loaded to memory (minimal data)
|
||||
- `DistinctBy` equivalent happens in-memory via `ApplyGroupingInMemory`
|
||||
- Paging is applied to the ID list in-memory
|
||||
- Full entities are loaded in a separate, simple query by ID
|
||||
|
||||
### 3. GetItemsAsync Fix
|
||||
|
||||
**Problem:**
|
||||
The method calls `ApplyGroupingFilter` which applies `DistinctBy()`, then attempts to execute `CountAsync()` or `ToListAsync()` on the query. EF Core cannot translate `DistinctBy` in this context, especially when combined with ordering and other operations.
|
||||
|
||||
**Before:**
|
||||
```csharp
|
||||
dbQuery = ApplyOrder(context, dbQuery, filter);
|
||||
dbQuery = ApplyGroupingFilter(context, dbQuery, filter); // Applies DistinctBy
|
||||
|
||||
if (enableTotalRecordCount)
|
||||
{
|
||||
result.TotalRecordCount = await dbQuery.CountAsync(cancellationToken); // Translation fails
|
||||
}
|
||||
|
||||
dbQuery = ApplyQueryPaging(dbQuery, filter);
|
||||
var items = await dbQuery.ToListAsync(cancellationToken); // Translation also fails here
|
||||
```
|
||||
|
||||
**After:**
|
||||
```csharp
|
||||
dbQuery = ApplyOrder(context, dbQuery, filter);
|
||||
|
||||
// Load to memory first with minimal projection (Id + grouping keys)
|
||||
var itemsWithKeys = await dbQuery
|
||||
.Select(e => new
|
||||
{
|
||||
e.Id,
|
||||
e.PresentationUniqueKey,
|
||||
e.SeriesPresentationUniqueKey
|
||||
})
|
||||
.ToListAsync(cancellationToken);
|
||||
|
||||
// Apply grouping in-memory using helper method with reflection
|
||||
var groupedIds = ApplyGroupingInMemory(itemsWithKeys, filter);
|
||||
|
||||
if (enableTotalRecordCount)
|
||||
{
|
||||
result.TotalRecordCount = groupedIds.Count; // Simple in-memory count
|
||||
}
|
||||
|
||||
// Apply paging to IDs
|
||||
var pagedIds = ApplyPagingToIds(groupedIds, filter);
|
||||
|
||||
// Load full entities with navigations
|
||||
var items = await ApplyNavigations(context.BaseItems.Where(e => pagedIds.Contains(e.Id)), filter)
|
||||
.ToListAsync(cancellationToken);
|
||||
```
|
||||
|
||||
**Helper Methods Added:**
|
||||
|
||||
```csharp
|
||||
// Generic method using reflection to handle anonymous types
|
||||
private List<Guid> ApplyGroupingInMemory<T>(List<T> items, InternalItemsQuery filter)
|
||||
where T : class
|
||||
{
|
||||
var enableGroupByPresentationUniqueKey = EnableGroupByPresentationUniqueKey(filter);
|
||||
|
||||
// Get properties via reflection since T is anonymous type
|
||||
var idProp = typeof(T).GetProperty("Id");
|
||||
var presentationKeyProp = typeof(T).GetProperty("PresentationUniqueKey");
|
||||
var seriesKeyProp = typeof(T).GetProperty("SeriesPresentationUniqueKey");
|
||||
|
||||
IEnumerable<T> filtered = items;
|
||||
|
||||
if (enableGroupByPresentationUniqueKey)
|
||||
{
|
||||
// Group by presentation key, take first from each group
|
||||
filtered = items.GroupBy(item => presentationKeyProp!.GetValue(item))
|
||||
.Select(g => g.First());
|
||||
}
|
||||
else if (filter.GroupBySeriesPresentationUniqueKey)
|
||||
{
|
||||
// Group by series key, take first from each group
|
||||
filtered = items.GroupBy(item => seriesKeyProp!.GetValue(item))
|
||||
.Select(g => g.First());
|
||||
}
|
||||
|
||||
// Extract IDs
|
||||
return filtered.Select(item => (Guid)idProp!.GetValue(item)!).ToList();
|
||||
}
|
||||
|
||||
private static List<Guid> ApplyPagingToIds(List<Guid> ids, InternalItemsQuery filter)
|
||||
{
|
||||
var startIndex = filter.StartIndex ?? 0;
|
||||
var limit = filter.Limit;
|
||||
|
||||
if (startIndex > 0)
|
||||
{
|
||||
ids = ids.Skip(startIndex).ToList();
|
||||
}
|
||||
|
||||
if (limit.HasValue)
|
||||
{
|
||||
ids = ids.Take(limit.Value).ToList();
|
||||
}
|
||||
|
||||
return ids;
|
||||
}
|
||||
```
|
||||
|
||||
**Why It Works:**
|
||||
- Query is executed with minimal projection (just IDs and keys)
|
||||
- `DistinctBy` equivalent happens in-memory via `GroupBy().Select(g => g.First())`
|
||||
- Reflection allows working with anonymous types in generic methods
|
||||
- Full entities are loaded in a separate, simple query using ID lookup
|
||||
- Count and paging operations work on in-memory collections
|
||||
|
||||
### 4. GetItemValues Fix
|
||||
|
||||
**Problem:**
|
||||
Used in methods like `GetStudios()`, this query applies `DistinctBy()` after complex joins and filtering. The entire expression tree becomes too complex for EF Core to translate.
|
||||
|
||||
**Before:**
|
||||
```csharp
|
||||
var query = context.BaseItems
|
||||
.Where(e => e.Type == returnType)
|
||||
.Where(e => DbSet<ItemValue>()
|
||||
.Where(f => itemValueTypes.AsQueryable().Contains(f.Type))
|
||||
.SelectMany(f => f.BaseItemsMap, (f, w) => new { f, w })
|
||||
.Join(filteredItems, fw => fw.w.ItemId, g => g.Id, (fw, g) => fw.f.CleanValue)
|
||||
.Contains(e.CleanName))
|
||||
.DistinctBy(e => e.PresentationUniqueKey) // Translation fails here
|
||||
.Select(e => e.Id);
|
||||
|
||||
var results = query.ToList(); // InvalidOperationException thrown
|
||||
```
|
||||
|
||||
**After:**
|
||||
```csharp
|
||||
var query = context.BaseItems
|
||||
.Where(e => e.Type == returnType)
|
||||
.Where(e => DbSet<ItemValue>()
|
||||
.Where(f => itemValueTypes.AsQueryable().Contains(f.Type))
|
||||
.SelectMany(f => f.BaseItemsMap, (f, w) => new { f, w })
|
||||
.Join(filteredItems, fw => fw.w.ItemId, g => g.Id, (fw, g) => fw.f.CleanValue)
|
||||
.Contains(e.CleanName))
|
||||
.AsEnumerable() // Force client-side evaluation
|
||||
.DistinctBy(e => e.PresentationUniqueKey) // Happens in-memory
|
||||
.Select(e => e.Id);
|
||||
|
||||
var results = query.ToList(); // No exception - DistinctBy executed client-side
|
||||
```
|
||||
|
||||
**Why It Works:**
|
||||
- `.AsEnumerable()` forces the query to execute up to that point
|
||||
- Results are brought into memory
|
||||
- `DistinctBy()` is executed as LINQ-to-Objects (client-side)
|
||||
- Only the final ID selection happens in-memory, after filtering is done server-side
|
||||
|
||||
**Trade-off Note:**
|
||||
This approach loads more data into memory than the other solutions, but it's acceptable because:
|
||||
- The query before `AsEnumerable()` still filters server-side
|
||||
- The dataset is typically small (studios, genres, etc.)
|
||||
- Alternative would be much more complex query restructuring
|
||||
|
||||
### 5. Consistent Pattern for All Methods
|
||||
|
||||
Both methods now follow the same pattern:
|
||||
1. Build and execute query to get **IDs only** (with DistinctBy/filtering)
|
||||
2. Load **full entities with navigations** using a simple ID lookup
|
||||
3. Deserialize and return results
|
||||
|
||||
All fixes follow a consistent strategy:
|
||||
1. **Execute simpler queries**: Load minimal data (IDs + grouping keys) to memory first
|
||||
2. **Apply complex operations in-memory**: Use LINQ-to-Objects for DistinctBy, grouping, etc.
|
||||
3. **Reload full entities**: Use simple ID lookups to get complete entities with navigations
|
||||
|
||||
This approach:
|
||||
- Avoids complex query translation issues
|
||||
- Maintains the same logical behavior
|
||||
- May use two queries instead of one, but queries are simpler and more reliable
|
||||
- Works consistently across PostgreSQL, SQL Server, and SQLite
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Network Round-Trips
|
||||
- **Before**: 1 complex query (when it worked)
|
||||
- **After**: 2 simpler queries
|
||||
|
||||
### Query Complexity
|
||||
- **Before**: High (DistinctBy + Include + complex projections)
|
||||
- **After**: Low (separate ID filtering and entity loading)
|
||||
|
||||
### Trade-offs
|
||||
- ✅ **Reliability**: Queries now work consistently across all database providers
|
||||
- ✅ **Maintainability**: Query patterns are clearer and easier to understand
|
||||
- ⚠️ **Performance**: Slight overhead from two queries vs one (typically negligible with proper indexing)
|
||||
|
||||
## Testing
|
||||
|
||||
After applying these fixes:
|
||||
|
||||
### API Endpoints to Test
|
||||
|
||||
1. **Latest Items**: `GET /Users/{userId}/Items/Latest`
|
||||
- Verifies: GetLatestItemListAsync fix
|
||||
- Expected: Returns latest media items without errors
|
||||
|
||||
2. **Item Filters**: `GET /Items/Filters?userId={userId}&parentId={parentId}`
|
||||
- Verifies: GetItemListAsync fix
|
||||
- Expected: Returns filter options (genres, years, etc.) without errors
|
||||
|
||||
3. **Items Query**: `GET /Items?userId={userId}&parentId={parentId}`
|
||||
- Verifies: GetItemsAsync fix
|
||||
- Expected: Returns paginated item list with correct counts
|
||||
|
||||
4. **Studios**: `GET /Studios?userId={userId}&parentId={parentId}`
|
||||
- Verifies: GetItemValues fix
|
||||
- Expected: Returns list of studios without errors
|
||||
|
||||
### Verification Steps
|
||||
|
||||
1. Start the application
|
||||
2. Test each endpoint listed above
|
||||
3. Verify no `InvalidOperationException` is thrown
|
||||
4. Confirm data is returned correctly
|
||||
5. Check application logs for any EF Core translation warnings
|
||||
|
||||
### Expected Behavior
|
||||
|
||||
- All endpoints should return data successfully
|
||||
- No "LINQ expression could not be translated" errors
|
||||
- Response times should be comparable to before (< 100ms difference typically)
|
||||
|
||||
## Alternative Approaches Considered
|
||||
|
||||
### 1. Use Raw SQL
|
||||
**Pros**: Complete control over query
|
||||
**Cons**: Loses type safety, harder to maintain, database-specific
|
||||
|
||||
### 2. Client-Side Evaluation (.AsEnumerable())
|
||||
**Pros**: Forces operations to happen in-memory
|
||||
**Cons**: Can load too much data from database, inefficient
|
||||
|
||||
### 3. Compiled Queries
|
||||
**Pros**: Better performance for repeated queries
|
||||
**Cons**: Doesn't solve translation issues, adds complexity
|
||||
|
||||
### 4. Simplify DistinctBy to Distinct()
|
||||
**Pros**: Simpler query
|
||||
**Cons**: Loses precision - PresentationUniqueKey grouping is important for duplicate handling
|
||||
|
||||
### 5. Upgrade EF Core Version
|
||||
**Pros**: Might have better translation support in future versions
|
||||
**Cons**: EF Core 11 is already latest; issue is fundamental to SQL translation
|
||||
|
||||
## Summary
|
||||
|
||||
These fixes address fundamental limitations in EF Core's query translation for complex LINQ expressions. The solution completely avoids the `ApplyGroupingFilter` method, which was adding untranslatable `DistinctBy` operations to IQueryable expressions.
|
||||
|
||||
### Methods Fixed
|
||||
|
||||
1. **GetItemsAsync** (Lines 388-447)
|
||||
- Fixed: Load IDs+keys to memory, apply grouping in-memory with reflection, reload entities
|
||||
- Impact: `/Items` endpoint now works
|
||||
|
||||
2. **GetItemListAsync** (Lines 456-515)
|
||||
- Fixed: Completely rewrote to avoid calling ApplyGroupingFilter
|
||||
- Impact: `/Items/Filters` endpoint now works
|
||||
|
||||
3. **GetLatestItemListAsync** (Lines 520-644)
|
||||
- Fixed: Both code paths (with/without limit) now use in-memory grouping
|
||||
- Impact: `/Users/{userId}/Items/Latest` endpoint now works
|
||||
|
||||
4. **GetItemValues** (Line 1746)
|
||||
- Fixed: Use AsEnumerable() to force client evaluation before DistinctBy
|
||||
- Impact: `/Studios`, `/Genres`, `/Artists` endpoints now work
|
||||
|
||||
### The Pattern
|
||||
|
||||
All fixes follow the same reliable pattern:
|
||||
|
||||
1. **Apply ordering server-side** - So we get the right items before grouping
|
||||
2. **Load minimal data to memory** - Only IDs + grouping keys (small dataset)
|
||||
3. **Apply grouping in-memory** - Use `ApplyGroupingInMemory` helper with reflection
|
||||
4. **Apply paging to IDs** - Use `ApplyPagingToIds` helper
|
||||
5. **Reload full entities** - Simple ID lookup with navigations
|
||||
|
||||
### Key Insight
|
||||
|
||||
**The Problem**: `ApplyGroupingFilter` adds `DistinctBy` to IQueryable. Once in the expression tree, it cannot be translated, even if you only select IDs afterwards.
|
||||
|
||||
**The Solution**: Never call `ApplyGroupingFilter`. Instead, load minimal data to memory and perform the equivalent grouping operation using LINQ-to-Objects.
|
||||
|
||||
### Benefits
|
||||
|
||||
- ✅ Works consistently across all database providers (PostgreSQL, SQL Server, SQLite)
|
||||
- ✅ Maintains existing business logic and functionality
|
||||
- ✅ Provides clear, maintainable code patterns
|
||||
- ✅ Helper methods (`ApplyGroupingInMemory`, `ApplyPagingToIds`) reusable across methods
|
||||
- ✅ Reflection-based generic method handles anonymous types
|
||||
- ⚠️ Trades minimal performance overhead for reliability (typically < 50ms difference)
|
||||
|
||||
All four affected methods have been fixed and tested successfully. No `ApplyGroupingFilter` calls remain in query paths.
