Multi-Repository Data Aggregation & Mapping Generator
0
Generate compile-time mapping pipelines that merge and enrich data from multiple repositories with access control logic
Added Dec 4, 2025
6 signals
The Problem
Developers building APIs with multiple data sources struggle with repetitive boilerplate for mapping entities to DTOs while enriching data with access controls and merging from different repositories. Existing tools don't handle multi-step enrichment pipelines well, leading to inconsistent patterns and error-prone code across teams.
Potential Solution
A .NET source generator and runtime library that lets developers declaratively define data pipelines using attributes. It automatically generates type-safe mapping, merging, and enrichment code at compile-time, handling complex scenarios like multi-repository aggregation and access control injection with zero runtime overhead.
Why Now?
Microservices and AI data pipelines (like RAG systems) have exploded data source complexity. .NET's modern source generators now enable sophisticated compile-time code generation that delivers both developer productivity and runtime performance, making this the perfect time for a next-generation mapping solution.
