Describe the feature
I would like to add an option to defineFunction to specify the size of ephemeral storage.
defineFunction({
entry: './test-assets/default-lambda/handler.ts',
ephemeralStorageSize: 1024, // <- like this
})See:
- https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_lambda.Function.html#ephemeralstoragesize
- https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-lambda-function-ephemeralstorage.html
Use case
When using defineFunction with Amplify Gen2, function has an ephemeral storage size of 512 MB.
I will get an error No space left on device when dealing with large size files in Lambda functions.
I would like to increase the size of the ephemeral storage with ephemeralStorageSize option.
