What counts as a lambda error?
Errors: The number of invocations that result in a function error. Function errors include exceptions thrown by your code and exceptions thrown by the Lambda runtime. The runtime returns errors for issues like timeouts and configuration errors. Limitations: The number of summon requests that are limited.

How to know if Lambda is invoked?
Lambda automatically monitors Lambda functions on your behalf and reports metrics through Amazon CloudWatch. To help you monitor your code as it runs, Lambda automatically tracks the number of requests, the invocation duration per request, and the number of requests that fail.
What is the maximum amount of RAM you can allocate to a lambda function?
AWS Lambda now supports up to 10 GB of memory and 6 vCPU cores for Lambda functions. AWS Lambda customers can now provision Lambda functions with a maximum of 10,240 MB (10 GB) of memory, a more than threefold increase from the previous limit of 3,008 MB.
What is the maximum length of a lambda function?
You can now configure your AWS Lambda functions to run for up to 15 minutes per run. Previously, the maximum execution time (wait time) for a Lambda function was 5 minutes.
What happens when you exceed the acceleration limit for a lambda function?
Privacy: Your email address will only be used to send these notifications. Once you exceed the throttling limit, Lambda functions that are called synchronously will return a throttling error (error code 429).
What happens when the concurrency limit in lambda is reached?
Each function can reserve a portion of the account’s attendance limit, which guarantees the function exactly that attendance. Otherwise, a function will run outside the unreserved concurrency limit. When the concurrency limit is reached, Lambda will not call a function and instead limit it.
How to speed up concurrency in AWS Lambda function?
You can reserve up to the unreserved account concurrency value shown, minus 100 for features that do not have reserved concurrency. To limit a function, set the reserved concurrency to zero. This stops processing any events until you remove the limit.
How can I retry a Lambda throttling request?
Change the configuration using the Lambda console or by calling the PutFunctionConcurrency API. As a best practice, retry throttled requests using exponential backoff in your application that is calling your Lambda function.
