Previously, users lacked a safe method to verify access permissions on streams, often sending engineered failing requests risking unintended data writes. The new 'DryRun' option lets clients confirm permissions and request validity without affecting production data.
When DryRun=true, successful permission checks return a specific exception confirming the request would have succeeded if executed. This feature covers key APIs and is available across all AWS regions, improving permission validation and deployment safety for stream-consuming applications.
