# Semantic Conventions for AWS DynamoDB **Status**: [Experimental][DocumentStatus] The Semantic Conventions for [AWS DynamoDB](https://aws.amazon.com/dynamodb/) extend and override the general [AWS SDK Semantic Conventions](/docs/cloud-providers/aws-sdk.md) that describe common AWS SDK attributes and the [Database Semantic Conventions](database-spans.md). that describe common database operations attributes in addition to the Semantic Conventions described on this page. ## Common Attributes These attributes are filled in for all DynamoDB request types. | Attribute | Type | Description | Examples | [Requirement Level](https://opentelemetry.io/docs/specs/semconv/general/attribute-requirement-level/) | Stability | |---|---|---|---|---|---| | [`db.system`](/docs/attributes-registry/db.md) | string | The value `dynamodb`. [1] | `dynamodb` | `Required` |  | **[1]:** The actual DBMS may differ from the one identified by the client. For example, when using PostgreSQL client libraries to connect to a CockroachDB, the `db.system` is set to `postgresql` based on the instrumentation's best knowledge. `db.system` has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used. | Value | Description | Stability | |---|---|---| | `other_sql` | Some other SQL database. Fallback only.
