Semantic Conventions for AWS DynamoDB

Status: Experimental

The Semantic Conventions for AWS DynamoDB extend and override the general AWS SDK Semantic Conventions that describe common AWS SDK attributes and the Database Semantic Conventions. 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	Stability
db.system	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.

[1]: This is the logical name of the method from the RPC interface perspective, which can be different from the name of any implementing method/function. The code.function attribute may be used to store the latter (e.g., method actually executing the call on the server side, RPC client stub method on the client side).

[2]: This is the logical name of the service from the RPC interface perspective, which can be different from the name of any implementing class. The code.namespace attribute may be used to store the latter (despite the attribute name, it may include a class name; e.g., class with method actually executing the call on the server side, RPC client stub class on the client side).

rpc.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
apache_dubbo	Apache Dubbo
connect_rpc	Connect RPC
dotnet_wcf	.NET WCF
grpc	gRPC
java_rmi	Java RMI
