The EF Core Cosmos DB provider handles JSON document materialization by mapping entity properties directly to JSON document structures. This process relies on a parallel query pipeline to efficiently retrieve and hydrate documents from Azure Cosmos DB.
To configure partition key usage and optimistic concurrency in EF Core for Cosmos DB, define partition keys during model configuration and enable ETag-based concurrency tracking. This ensures proper document routing and safe concurrent updates within the Cosmos provider.
No, the EF Core Cosmos DB provider does not support database migrations like relational providers. Because it uses document-centric storage, it omits migrations, cross-container joins, and relational schema management paradigms entirely.
The best way to plan code changes for EF Core Cosmos-specific features involves outlining a minimal patch plan that respects query generation and configuration rules. Contributors must review provider internals to modify Cosmos-specific code safely and efficiently.
The EF Core Cosmos DB provider lacks cross-container joins because it operates on a document-centric storage model rather than a relational schema. This architectural difference means queries are scoped to individual containers, omitting relational join capabilities.
