Remove misleading payload signing performance warnings - #778
Merged
Conversation
Payload signing is enabled by default and the warning is emitted for every non-empty request body, including small requests where the performance impact is negligible. Remove the noisy warning from both synchronous and asynchronous signers.

Summary
Remove
AWSSDKWarningemissions from the synchronous and asynchronous SigV4 signers when hashing request payloads.Payload signing is enabled by default, and the warning was emitted for every non-empty request body regardless of size. This made normal SDK operations, including small STS requests, produce a noisy and non-actionable warning.
Payload signing behavior remains unchanged and only the warning is removed. Tests are updated accordingly.
