Is this project alive?

[tbarbugli]

I dont see much activity plus my first attempt on a Go project using modules fails on import errors

Is this the best way to use DAX with Golang?

Yes, this package is still alive. As your IDE is showing you, you should not be importing the internal folder.

This might be a helpful stack overflow response: https://stackoverflow.com/questions/59342373/use-of-internal-package-not-allowed

The README shows an example of importing the aws-dax-go package to your project.

If there is a different issue here and I misunderstood, please reopen the ticket.

It looks like the version of aws-sdk-go that you are using is behind the version required by aws-dax-go. The types that are undefined were added in version 1.35.34 of aws-sdk-go. Try go get github.com/aws/aws-sdk-go.

For an example of how to use the client, see the code in github.com/aws-samples/aws-dax-go-sample. The comment above about not importing the internal packages of aws-dax-go is correct.

@ktseytlin the screenshot is from the vendor/github.com/aws/aws-dax-go/dax/api.go file not from my project

@kevinchristen I will try to upgrade to latest of aws-sdk-go, I am using Go modules btw. The deps you have on the repo are also out of date:

[[constraint]]
  name = "github.com/aws/aws-sdk-go"
  version = "1.30.7"

FTR I did not mean to sound provocative but I see so many issues with this lib that I was wondering if it was still alive and well, happy to help out with feedback if it gets answered :)

[kevinchristen]

We are happy for the feedback; don't worry about sounding provocative. Can you clarify if you have been able to get past the problems reported above by updating aws-sdk-go and not trying to import the internal packages of aws-dax-go? If not, what problems are you seeing now? Please share your code if you can (not just a screenshot). Thanks.

I found out the issue, our project is using go modules and has aws-sdk to ~1.33. I am not 100% sure but I this might be related to the fact that this lib does not have a go.mod manifest.

Probably a good idea to make this into a go module (when you do be careful because the dep dependency file will be used by go mod init and that manifest is using 1.30.7 :))

One thing I noticed is that DAX and DynamoDB have slightly different methods to construct their clients (New / NewWithSession, Session vs *Session)

func GetDynamo() *dynamodb.DynamoDB {
    config := &aws.Config{}

    sess := session.Must(session.NewSession(config))
    svc := dynamodb.New(sess)
    return svc
}

func GetDAX() (*dax.Dax, error) {
    config := &aws.Config{}

    sess := session.Must(session.NewSession(config))
    client, err := dax.NewWithSession(*sess)
         return client, err
}

We added support for go modules to this and the aws-dax-go-sample repository. Thanks for the advice; I hope that eliminates the problems with mismatched versions.
