A Contract Pattern for Schemaless DataStores

This article discusses the challenges of serializing discriminated union types in event-sourced systems and introduces a generic, boilerplate-reducing pattern using the UnionContract module from the TypeShape library. It provides code examples in F# for encoding/decoding events and explains how to achieve a canonical, serialization-agnostic representation for union types.
