feederlayer
Feederlayer is a software architectural layer that aggregates data from multiple external and internal sources and exposes a stable, uniform interface to upper layers of an application. It acts as an intermediary between data sources such as databases, APIs, message queues, and file systems and the domain or processing layers, shielding them from source-specific formats and protocols.
Core responsibilities include building source adapters, orchestrating data ingestion, performing data validation, normalization and schema mapping,
Placement and design vary. In some architectures, the feeder layer sits as a dedicated microservice or library
Benefits include decoupling of data sources from business logic, easier testing and replacement of sources, centralized
Common patterns include adapter-based connectors, a canonical data model, and a service-oriented or event-driven interface that
