The structural problem DCB solves: business rules that span multiple aggregates and cannot be defended by per-stream optimistic concurrency.
We build the coupon redemption command from Part 1 using Marten's DCB API: tag types, BoundaryAggregate, FetchForWritingByTags, and the explicit ConcurrencyException retry cycle.
We rebuild the redemption command from Part 2 using Wolverine.HTTP with a [WolverinePost] endpoint, where the HTTP route, the DCB consistency boundary, and the business decision live in one static method. Includes an Alba HTTP test.
Tag storage modes, the global-lock failure mode of over-broad queries, tag governance, schema evolution, incremental migration from existing aggregates, and when DCB is the wrong tool.

This is a continuation of the Marten native partial updates patching post. All the native patch operations are driven by a bunch of custom PL/pgSQL functions with prefix mt_jsonb_. Marten uses JSONB for all its JSON storage hence all th...
Partial update or patching JSON involves making changes to specific parts of a JSON document without replacing the entire document. This is particularly useful when you only need to modify certain fields or elements within a large JSON object, rather...
