Description

Adds Boto3Integration(propagate_traces=True). Setting it to False stops the integration from changing the request params of AWS calls:

• Lambda Invoke no longer gets trace data in ClientContext.
• Once feat(boto3): Add SQS/SNS trace propagation #8145 lands: SQS SendMessage / SendMessageBatch and SNS Publish / PublishBatch no longer get sentry-trace / baggage message attributes, and SQS ReceiveMessage no longer appends our names to MessageAttributeNames.

The option gates the shared get_request_params hook, so it covers every extension that uses it without per-service changes. Spans are still created as before.

This is an escape hatch for setups where the added data breaks calls, e.g. a queue or topic whose MaximumMessageSize is set below the 256 KiB the #8145 size check assumes, or consumers that reject unknown attributes. The name matches CeleryIntegration(propagate_traces=...).

HTTP sentry-trace / baggage headers on AWS requests are not affected. They're also added by the stdlib integration and are already controlled by trace_propagation_targets.

Independent of #8145. The SQS/SNS test cases pass trivially until #8145 is merged, and guard the option after that. Whichever PR merges second needs a small conflict fix at the end of test_trace_propagation.py, since both append tests there.
