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 - 实战步骤 2. 修改Lambda函数 - 修改timeout参数 ...
本文承接《AWS Lambda provisioned concurrency预配置并发 下篇》一文,接着利用Lambda函数“NewtstestBash-runtime”测试用Application Auto Scaling(Asg)来管理provisioned concurrency(预配置并发)。 目录 实战步骤 修改Lambda函数 注册scaling target 为scaling target设置scaling policy 测试provisioned concurrency 修改scali...
ProvisionedConcurrencyInvocations –Lambda 使用预置并发调用函数代码的次数。Lambda 会根据配置的预置并发,为每个函数版本和别名发送该指标。使用 SUM 查看该指标。 ProvisionedConcurrencyInvocations 与ProvisionedConcurrentExecutions 的不同之处在于,ProvisionedConcurrencyInvocations 会计算调用总次数,而 ProvisionedConcurrent...
Lambda functions linked to an Amazon MQ event source mapping have a default maximum concurrency. For Apache Active MQ, the maximum number of concurrent instances is 5. For Rabbit MQ, the maximum number of concurrent instances is 1. Setting reserved or provisioned concurrency for your function doe...
This difference is due to the cold start, when the Lambda service prepares new execution environments to absorb the load during the peak. Using Provisioned Concurrency at noon can avoid this additional latency and provide a better experience to end users. Ideally, it should also ...
1.前往AWS Lambda控制台,而后选择您的现有Lambda函数。 2.Provisioned concurrency的设置必须明确指向已发布的版本或者别名。前往Actions下拉菜单,并选择Publish new version。 3.选择Publish. 向下滚动至Concurrency面板并选择Add Configuration。 4.输入首选并发,而后选择Save。
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。
New for AWS Lambda – Predictable start-up times with Provisioned Concurrency https://aws.amazon.com/cn/blogs/compute/new-for-aws-lambda-predictable-start-up-times-with-provisioned-concurrency/ Announcing improved VPC networking for AWS Lambda functions ...
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 ...
SinceAWS Lambda now enables the use of ECMAScript (ES) modulesin Node.js 14 runtimes, you could lower the cold start latency when used withProvisioned Concurrencythanks to the top-level await functionality. We can use this by calling thefastify.ready()function outside of the Lambda handler ...
