What problem does it solve?

This skill enables teams to efficiently compose multiple Marten projections by constructing a Composite Projection, reducing data processing time and simplifying projection pipelines.

Core Features & Use Cases

  • Composite Projection: Chains multiple projections into a single, efficient read path.
  • Staged Projections: Supports Stage 1 basic projections and Stage 2 dependent projections that consume outputs from Stage 1.
  • Indexing Best Practices: Aligns with Marten's indexing to optimize throughput and query performance.

Quick Start

Follow these steps to implement a composite projection in Marten (v8.18+): define the Projection class in src/BookStore.ApiService/Projections/, configure MartenConfigurationExtensions.cs with options.Projections.CompositeProjectionFor(...) to add Stage 1 and Stage 2 projections, and verify indexing in ConfigureIndexes.
