AWS serverless-application-model documentation change

Service: serverless-application-model · 2025-11-22 · Documentation low

File: serverless-application-model/latest/developerguide/sam-property-function-selfmanagedkafka.md

Summary

Added same new configuration properties as MSK file and increased maximum pollers from 20 to 2000, fixed documentation links

Security assessment

The changes mirror those in the MSK documentation, adding error handling parameters and scaling capabilities. The corrected link and 'minimum' spelling fix are maintenance updates. No security vulnerabilities or explicit security features are addressed in the changes.
