I would like to test aws lambda limits locally with serverless-offline. When I ran this code I expected to see an error (TooManyRequestsException) but all request are sent successfully. Am I missing something, or is it not possible to test aws limits with serverless-offline?
const lambda = new Lambda({
apiVersion: '2031',
region: 'us-east-1',
endpoint: 'http://localhost:3002',
})
async function runMultipleLamdas() {
const params = {
// FunctionName is composed of: service name - stage - function name, e.g.
FunctionName: 'simple-http-endpoint-dev-currentTime',
InvocationType: 'RequestResponse',
Payload: JSON.stringify({ data: 'foo' }),
}
Promise.all(Array(10000).fill(lambda.invoke(params).promise())).then(
(values) => {
console.log(values)
}
)
}
runMultipleLamdas()
serverless-offline doesn't simulate the AWS service quota for concurrent Lambda function executions. The AWS default quota value of 1,000 concurrent execution per region is a soft limit anyway, and can be raised through the AWS Service Quotas console.
