Implement Serverless Service Representation (SSR) in AWS Lambda #7850

rithikanarayan · 2025-11-20T21:05:28Z

Summary of changes

Fixes the Serverless Service Representation (SSR) for Dotnet.
In serverless environments, sets peer.service tag for outbound AWS managed service spans to {service type}.{region}.amazonaws.com:

SQS: sqs.us-east-1.amazonaws.com
SNS: sns.us-east-1.amazonaws.com
Kinesis: kinesis.us-east-1.amazonaws.com
Eventbridge: events.us-east-1.amazonaws.com
s3: bucket-name.s3.us-east-1.amazonaws.com
Dynamodb: dynamodb.us-east-1.amazonaws.com

Sets peer.service.source to peer.service for these serverless cases.
Adds DerivePeerService function in Util/PeerServiceHelpers to do the above assignment.

Reason for change

Comparison explanation

Execution-time benchmarks measure the whole time it takes to execute a program, and are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are highlighted in **red**. The following thresholds were used for comparing the execution times:

Welch test with statistical test for significance of 5%
Only results indicating a difference greater than 5% and 5 ms are considered.

Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard.

Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph).
