AWS CLI 2.2.17 如果 aws 版本太低还需要手工安装插件,建议升级到高版本 Python 3.8 实战步骤 2. 修改Lambda函数 修改timeout参数 我们先把上篇中创建的Lambda函数的timeout修改得大一些。 进入Lambda控制台,选择我们在《AWS Lambda自定义运行环境测试 下篇》一文创建的函数“tstestBash-runtime”,选择“Configuration...
本文承接《AWS Lambda reserved concurrency预留并发》一文,介绍Lambda函数另外一种并发控制——provisioned concurrency(预配置并发)。 本文会利用《AWS Lambda自定义运行环境测试 下篇》一文中的环境来查看执行环境的启动任务对函数的影响,在下一篇中我们会测试预配置并发。 目录 Lambda provisioned concurrency预配置并发 ...
Lambda emits this metric for all functions, versions, and aliases. For any function in the Lambda console, Lambda displays the graph for ConcurrentExecutions natively in the Monitoring tab, under Metrics. View this metric using MAX. UnreservedConcurrentExecutions –The number of active concurrent ...
For example, to configure reserved concurrency with the AWS Command Line Interface (CLI), use theput-function-concurrencycommand. The following command reserves 100 concurrency units for a function namedmy-function: aws lambda put-function-concurrency--function-namemy-function\ --reserved-concurrent-ex...
AWS Lambda now provides a way to control the maximum number of concurrent functions invoked by Amazon SQS as an event source. You can use this feature to control the concurrency of Lambda functions processing messages in individual SQS queues. This post describ...

If you were trying to use Lambda in a use case that was very latency sensitive, cold starts were probably your greatest concern. AWS has heard the concerns
First off, I have to say I find AWS Lambda an extremely useful way to build application components in an agile and reliable way. AWS Lambda is a service that allows you to upload code to the cloud and run it without having to maintain its underlying infrastructure. You pay for the ...
