本文承接《AWS Lambda provisioned concurrency预配置并发 上篇》一文,测试provisioned concurrency(预配置并发)。 本文会在WSL环境中使用AWS CLI来触发Lambda函数。有关AWS CLI的配置可以参考《AWS CLI SSL: CERTIFICATE_VERIFY_FAILED 错误分析与解决》一文。 目录
在 Lambda 中,并发是您的函数同时处理的正在进行的请求数。一种衡量 Lambda 函数并发的快速而实用的方法是使用以下公式: Concurrency = (average requests per second) * (average request duration in seconds) 并发不同于每秒的请求数。例如,假设您的函数平均每秒接收 100 个请求。如果平均请求持续时间为一秒,那么...
Lambda provisioned concurrency预配置并发 我们知道Lambda函数有两种控制并发(concurrency)的方法 reserved concurrency:预留并发,保证Lambda函数可以使用的最大并发数(也就是instances数量)。当一个函数设置了reserved concurrency,那么其它函数就不可以占用被保留的concurrency,即其它函数可使用的并发数就会相应减少。函数配置res...
To intentionally throttle a function, set its reserved concurrency to 0. This stops your function from processing any events until you remove the limit. To configure reserved concurrency with the Lambda API, use the following API operations. ...

AWS_LAMBDA_DOTNET_PREJIT– 对于 .NET 3.1 运行时,设置此变量以启用或禁用 .NET 3.1 特定的运行时优化。值包括 always、never和provisioned-concurrency。 TZ– 环境的时区 ( UTC)。执行环境使用 NTP 来同步系统时钟。 显示的示例值反映了最新的运行时。特定变量的存在或其值在早期运行时可能会有所不同。
In situations where a Lambda function’s executions are higher than the number of Provisioned Concurrency, this metric will show the number of executions above Provisioned Concurrency. Ideally, it should be zero, therefore it’s recommended to trigger an alarm when this value is > 0. Enable ...
