Description: SAM Template for StreamingfromEvent Example

# This is an example SAM template for the purpose of this project.
# When deploying such infrastructure in production environment,
# we strongly encourage you to follow these best practices for improved security and resiliency
# - Enable access loggin on API Gateway
#   See: https://docs.aws.amazon.com/apigateway/latest/developerguide/set-up-logging.html)
# - Ensure that AWS Lambda function is configured for function-level concurrent execution limit
#   See: https://docs.aws.amazon.com/lambda/latest/dg/lambda-concurrency.html
#        https://docs.aws.amazon.com/lambda/latest/dg/configuration-concurrency.html
# - Check encryption settings for Lambda environment variable
#   See: https://docs.aws.amazon.com/lambda/latest/dg/configuration-envvars-encryption.html
# - Ensure that AWS Lambda function is configured for a Dead Letter Queue(DLQ)
#   See: https://docs.aws.amazon.com/lambda/latest/dg/invocation-async-retain-records.html#invocation-dlq
# - Ensure that AWS Lambda function is configured inside a VPC when it needs to access private resources
#   See: https://docs.aws.amazon.com/lambda/latest/dg/configuration-vpc.html
#   Code Example: https://github.com/awslabs/swift-aws-lambda-runtime/tree/main/Examples/ServiceLifecycle%2BPostgres
