Missing table_name detail when instrumenting AWS SDK v2 and using DynamoDB Service

[farazoman]

Problem

Given implementing aws sdk v2 golang library and using the awsv2.AWSV2Instrumentor to initialize x-ray.
When running a command like PutItem (with context and put request)
Then the trace info does NOT show the table_name

Expected

that it should work same or at least similar to v1 library, where the table_name is displayed under the aws key for specific metadata which s what I understand is displayed on the Trace Map feature

Actual

only three fields are shown under the aws key; region, operation, request_id

I was reviewing this issue: #320 which seems related but it doesn't specifically mention the table_name value

Hi @farazoman,

can you provide a code sample of the issue to reproduce it? Can you also provide the PutItem request that you're sending the DynamoDB?

Based on the go xray sdk code, the table_name should be visible in the tracing:

Hey @liustve ,

So this is the relevant code that I have:

	"github.com/aws/aws-sdk-go-v2/service/dynamodb"
	"github.com/aws/aws-sdk-go-v2/service/dynamodb/types"
	"github.com/aws/aws-sdk-go/aws"
	"github.com/aws/aws-xray-sdk-go/instrumentation/awsv2"

...main(...)...
        // cx comes from main function signature
	awsCfg, err := methodToGetConfig(cx)

	awsv2.AWSV2Instrumentor(&awsCfg.APIOptions)
	dynamoClient := dynamodb.NewFromConfig(awsCfg)

	item := map[string]types.AttributeValue{
		"Id": &types.AttributeValueMemberS{
			Value: uuid.New().String(),
		},
	}

	input := &dynamodb.PutItemInput{
		TableName: aws.String("<table_name>"),
		Item:      item,
	}

	_, err = dynamoClient.PutItem(ctx, input)

When looking at the raw segment, this is the subsegment data

                            {
                                "id": "<some_id>",
                                "name": "DynamoDB",
                                "start_time": 1741988803.491925,
                                "end_time": 1741988803.5702703,
                                "http": {
                                    "response": {
                                        "status": 200,
                                        "content_length": 2
                                    }
                                },
                                "aws": {
                                    "region": "<aws_region>",
                                    "operation": "PutItem",
                                    "request_id": "<request_id>"
                                },
                                "namespace": "aws"
                            }

Note when I use sdkv1 + the xray client wrappers, the table_name does show up.

Thanks!
