Scanning the table returns the map of items and you want to convert map into the struct so in order to convert the list of maps to the struct you want to use attributevalue.UnmarshalListOfMaps under aws-sdk-go-v2. In the previous version it was in the dynamodbattribute but they decided to change the package in the v2.

since the handler function expectes interface the request is passed as map[string]interface{} after I changed the type of the request parameter to events.APIGatewayProxyRequest my code automatically started to receive in this type.

Based on your code snipped, it looks as if you are using the AWS SDK for Go V2. It is recommended to use the AWS SDK for Go V2 (please review the Migrating to the AWS SDK for Go V2 documentation).

Please initialize a Go Modules project (as described on the SDK's Github page):

How to connect Golang Lambda function with Redis Elasticache AWS

Asked 2021-Sep-13 at 16:20

I'm new with golang.

I've been looking documentation of lambda-golang-AWS and still had this timeout in when invoking the function.

I've been configuring:

Elasticache cluster (1 primary node),
VPC (one same VPC for redis and lambda),
Security groups,
Subnets,
Inbound and outbound,
role

I have this primary Redis endpoint xxxxxx

I just need an example.

So, my questions are:

Can we connect Redis in Linux without an EC2 instance? Possibly try it with RDM.
How do we put AWS redis's endpoint in the main function? (do we only need the endpoint? or else)
Is it possible to connect to Redis Elasticache with only endpoint (without AUTH)?

Thanks a lot!

Can we connect Redis in Linux without an EC2 instance?

Yes, of course, why would an EC2 instance be an additional requirement? You just need to include a Redis client library in your Lambda function's deployment artifact, and configure the Elasticache cluster to allow inbound traffic from the security group assigned to the Lambda function.

How do we put AWS redis's endpoint in the main function? (do we only need the endpoint? or else)

I would configure the endpoint as one of the Lambda function's environment variables.

Is it possible to connect to Redis Elasticache with only endpoint (without AUTH)?

If you don't enable AUTH on Elasticache, then you can connect without AUTH. AUTH is an optional configuration setting.

To get the two numbers you would have to fetch them from the map. If you always know the key and you know that there will only be one element in the array you can do it like this

Though i am not familiar with the lambda GUI i suspect that there you input the json representation of the request (with headers and body), but when sending via curl, you don't need to wrap the body (-d), so just send it like this [{\"id\":\"123\"}] as this is what the body should contain.

ANSWER

Answered 2021-Aug-14 at 20:26

When you proxy the request through some other AWS event source, the payload sent to the lambda gets wrapped into an event object.

In the case of API Gateway, the payload is a events.APIGatewayProxyRequest, which is not a slice, and can't be marshalled into a []interface{}.

The aws-lambda-go github repo has a piece of documentation that shows how to build the handler. In short:

QUESTION

func init() vs func main() for initalizing global state in AWS Lambda handlers

Asked 2021-Jun-03 at 16:35

Looking at the Using global state section in the official AWS Lambda function handler in Go doc https://docs.aws.amazon.com/lambda/latest/dg/golang-handler.html

suggests to initialise all global state in func init() i.e. Any package level vars which we want to share across multiple lambda invocations go here.
And my understanding is that this initialisation is done once per lambda container start (i.e cold start).

My question is, is it possible to do the same using func main() instead of func init().
Using func init() basically makes my handler function (func LambdaHandler) non unit-testable due to side-effects from func init() running.
Moving the func init() code to func main() seems to solve this easily.
Are there any side effects to using func main() vs func init()
