v3.0.0

DataFuse v3.0.0 Release Notes

Release Date: March 30, 2026

DataFuse v3.0.0 is a major release that introduces the new MongoDB adapter, transform hooks, query result caching, and multi-target framework support. This release also completes the project rebrand from Schemio to DataFuse, which includes breaking namespace and package changes.

New Features

MongoDB Adapter

New DataFuse.Adapters.MongoDB package for aggregating data from MongoDB collections alongside SQL, REST API, and Entity Framework sources.

• Built on MongoDB Driver 3.4.0
• Implements the same query/engine pattern as other adapters
• Register via .WithEngine(c => new DataFuse.Adapters.MongoDB.QueryEngine(mongoDatabase))

public class ReviewsMongoQuery : MongoQuery<CollectionResult<ReviewResult>>
{
    protected override Func<IMongoDatabase, Task<CollectionResult<ReviewResult>>> GetQuery(
        IDataContext context, IQueryResult? parentQueryResult)
    {
        var product = (ProductResult)parentQueryResult;
        return async database =>
        {
            var collection = database.GetCollection<ReviewResult>("reviews");
            var reviews = await collection.Find(r => r.ProductId == product.Id).ToListAsync();
            return new CollectionResult<ReviewResult>(reviews);
        };
    }
}

Transform Hooks

Pre and post transformation hooks provide fine-grained control over the data transformation pipeline.

• PreTransform hooks execute before a transformation and can cancel it via context.Cancel()
• PostTransform hooks execute after a transformation and can request repetition via context.Repeat()

Query Result Caching

New CacheResultAttribute allows marking expensive query results for automatic caching to improve performance.

Multi-Target Framework Support

All packages (except EntityFramework) now target multiple frameworks:

• netstandard2.1
• net8.0
• net9.0
• net10.0

DataFuse.Adapters.EntityFramework targets net10.0 only (EF Core 10.0 dependency).

Breaking Changes

Project Rename (Schemio to DataFuse)

All namespaces, packages, and registration APIs have been renamed:

v2.x (Schemio)	v3.0.0 (DataFuse)
Schemio.Core (contracts)	DataFuse.Adapters.Abstraction
Schemio.Core (impl)	DataFuse.Integration
Schemio.SQL	DataFuse.Adapters.SQL
Schemio.EntityFramework	DataFuse.Adapters.EntityFramework
Schemio.API	DataFuse.Adapters.WebAPI

DI Registration

// Before (v2.x)
services.UseSchemio(new SchemioOptionsBuilder() ...);

// After (v3.0.0)
services.UseDataFuse(new DataFuseOptionsBuilder() ...);

Interface Renames

• ISchemioOptions → IDataFuseOptions
• SchemioOptionsBuilder → DataFuseOptionsBuilder

NuGet Package Names

All package IDs have changed. Update your package references:

Old Package	New Package
Schemio.Core	DataFuse.Adapters.Abstraction
Schemio.Core	DataFuse.Integration
Schemio.SQL	DataFuse.Adapters.SQL
Schemio.EntityFramework	DataFuse.Adapters.EntityFramework
Schemio.API	DataFuse.Adapters.WebAPI

---

Migration Guide

1. Update NuGet packages to the new DataFuse.* package names
2. Update using statements from Schemio.* namespaces to DataFuse.*
3. Update DI registration from UseSchemio() to UseDataFuse() and SchemioOptionsBuilder to DataFuseOptionsBuilder
4. Update target framework if needed — packages now support netstandard2.1, net8.0, net9.0, and net10.0
