Configuration¶
The DynamoDB EF Core provider is configured through DbContextOptionsBuilder and a set of fluent
APIs for mapping entities to tables and keys.
In This Section¶
Client Setup¶
Configure the IAmazonDynamoDB client the provider uses for all SDK calls. You can supply a
pre-built client instance, a base AmazonDynamoDBConfig, or an inline callback to set the
endpoint, region, and credentials. This page also covers pointing at DynamoDB Local for local
development and testing.
DbContext Options¶
Register the provider via UseDynamo and tune the runtime behavior: transaction overflow
strategy, maximum transaction and batch sizes, automatic index selection mode, and per-context
overrides through the DatabaseFacade extension methods.
Table and Key Mapping¶
Map each entity type to a DynamoDB table and declare which properties serve as the partition key and optional sort key. Covers both convention-based key discovery and explicit fluent configuration, the key property requirements, and the model validation errors the provider raises at finalization.
Table Lifecycle¶
Use EnsureCreatedAsync and EnsureDeletedAsync for explicit DynamoDB table lifecycle operations,
including missing table creation, GSI updates, LSI limitations, async-only APIs, and seeding
behavior.
Attribute Naming¶
Control how CLR property names translate to DynamoDB attribute names. The provider applies CamelCase by default; you can switch to a different built-in convention, supply a custom naming function, or override individual scalar, complex-property, or complex-collection attribute names explicitly.
