Lambda Caching Layer

Hello,

I'm using AWSSecretsManagerConfigurationExtensions with api running on Lambda. But i'm now facing the issue where the GetSecretValue limit of 10k read/seconds is reached.

I saw AWS provide a cache layer for secret and parameter that can be dirrectly link to a lambda function :
https://docs.aws.amazon.com/secretsmanager/latest/userguide/retrieving-secrets_lambda.html

For example you can add this layer to your function with cloudformation like this :

      Layers:
        - arn:aws:lambda:eu-central-1:187925254637:layer:AWS-Parameters-and-Secrets-Lambda-Extension-Arm64:4

Actually AWSSecretsManagerConfigurationExtensions is reading secret at each application start. in the case of .net api running on lambda, each invocations is reading secret.

Can we imagine an implementation of the cache layer of lambda ?

Regards

Start with AWSSecretsManagerConfigurationExtensions and compare its current secret retrieval behavior with the AWS Parameters and Secrets Lambda Extension described in the linked documentation. Define how the cache layer should be enabled and used for Lambda invocations, then verify that repeated invocations no longer call GetSecretValue each time.
