If I understand the time line correctly v1 of the SDK was in developer preview for just a couple of months. V2 has been in developer preview for almost a year now. It would help if we know the timeline when this would be production ready.
Pawel Lekki
Hello guys, is it possible that v2 is significantly slower than v1. After upgrading to v2 calling dynamodb.GetItem by PK is no longer single digit ms. We're seeing at least 20ms performance degradation.

hey all
given an Instance struct, how do i determine the amount of memory it has? Do i need to maintain my own mapping of instanceType and memorySize?
I am able to determine core count with the CpuOptions attribute in this struct. But seems like there nothing for memory
hey all, glad to discover the room
newbie question here: is there a main 'Go' or 'Golang' room, I can join for non-AWS-sdk questions?
Kai Hendry
@jasdel wrt to the S3 API, should we be using s3manager to upload files as a rule?
Jason Del Ponte
@kaihendry correct, in general the S3manager will provide a better experience and retry capability that the S3 API's directly.
Kai Hendry
@jasdel thanks, I'll try use pointer receivers more then aws/aws-sdk-go-v2#263

Anyone having issues with connection churn when talking to AWS services (even though the various http client KA parameters are set correctly, including MaxConnsPerHost)? We're doing 1000s of requests per second, and churning connections, eventually leading to ephemeral port exhaustion. Digging into why the stdlib httpclient is closing the connection is because the connection never got an EOF, even though we got a full response and no error back from the API call.
Hello, I am doing an AppSync project and I wanted to access the Context.Identity ... is there a defined Struct ? or should i simply map it to a map[string] interface{} ?
anyone know if can use aws lambda to create a proxy (without the apigateway, just a lambda function)?
Hello, could anyone kindly point me to the v2 api reference for the aws sdk, ie v2 of this - https://docs.aws.amazon.com/sdk-for-go/api/
Kai Hendry
@bee-keeper something like https://godoc.org/github.com/aws/aws-sdk-go-v2 ?
hi I am using elbv2 and trying to list classic elbs and its not working. Is there a way to list elbs with elbv2 using aws-sdk-go-v2 ?. Please let me know
Kai Hendry
@jasdel how best to allow users to toggle AWS_PROFILE? https://github.com/unee-t/5xx
Topher Sterling
Could we get a link to the Go docs (https://godoc.org/github.com/aws/aws-sdk-go-v2 ) added to the GitHub README for aws-sdk-v2?
Topher Sterling
The search results from google don't bring it up
And you can only find the v1 docs on the AWS website
Hi, I'd like to create PR regarding issue 227 - aws/aws-sdk-go-v2#227
but all of the services are autogenerated (it says do not edit)
ok, looks like it is models/apis/...
are you guys planning on changing this codegen style? it doesn't seem to be very flexible ...
Nick Brandaleone
Question. Is there an idiomatic way in the Go v2 SDK, to enumerate all regions? I wish to iterate through various resources in all regions, and I am curious if things have changed between v1/v2 in terms of process.
Kai Hendry
@nbrandaleone i go through the regions here: https://github.com/kaihendry/goserverless.sg/blob/master/main.go

Hello. I am getting a "ThrottlingException" when doing a dynamodb PutItemRequest.Send(). I believe this is because my pay per request table is being resized automatically. My problem is I don't see a ThrottlingException defined in the service/dynamodb/errors.go file. I see it defined for many other services. I could just use one of the constants defined for another service since it is just a string but I am wondering if I am "doing it wrong" somehow.
Jason Del Ponte
@delbaeth you're correct. The model for the DynamoDB API does not include references to the ThrottlingException. I can forward this to the DynamoDB team, to see if they can update the model
guys, how can i encode a configservice.ConfigurationItem into a map[string]interface{} while using the tag locationName: to assign correct keys
Søren Dalby Larsen
Hi. Do I need to do anything in the config to make use of an s3 endpoint in a VPC. And if so, what?
Thomas Symborski
apologies if I'm missing something obvious, I've just started using the new SDK to manage MediaConvert. The first request I'm making (ListJobs) seems result in a nil deref exception because the HTTPResponse has not been set, further investigation shows the list of handlers for the Send action is empty, is this a misconfiguration on my part?
Thomas Symborski
example code for the above:
    ctx := context.Background()

    client := mediaconvert.New(aws.Config{
        Region: "filtered",
        Credentials: &aws.SafeCredentialsProvider{
            RetrieveFn: func() (aws.Credentials, error) {
                return aws.Credentials{
                    AccessKeyID:     "filtered",
                    SecretAccessKey: "filtered",
                }, nil
        EndpointResolver: &aws.ResolveWithEndpoint{
            URL: "filtered",

    resp, err := client.ListJobsRequest(nil).Send(ctx)
    spew.Dump(resp, err)
Thomas Symborski
after some more exploration, if I set the config using cfg, err := external.LoadDefaultAWSConfig() and then change the bits that I don't want pulled from the env, things seem to work
another anecdotal thing, if you have a trailing slash in your endpoint, the APIs fail with a non-obvious 403 error
Is there any schedule about V2 release?
I mean when it will be production ready.
Erik Swanson
Anyone have any ideas re this? (Affects the README.md example, aws cli and v1 sdk are OK), the completely empty "caused by" is confusing:
panic: failed to describe table, EC2RoleRequestError: no EC2 instance role found
caused by: EC2MetadataError: failed to make Client request
caused by:

goroutine 1 [running]:
What is really making no sense is that I get no output even from adding cfg.LogLevel = aws.LogDebugWithHTTPBodybefore the dynamo stuff.
Erik Swanson

How do you mock the Send function for kinesis in v2? I'm experimenting with using kinesisiface as recommended here https://github.com/aws/aws-sdk-go-v2/blob/master/service/kinesis/kinesisiface/interface.go ; but one thing that isn't provided in that interface is the Send function for a PutRequestRecord.
Roberto Guerra
How does one create a Config? I thought that a CredentialsProvider would be automatically created based on the AWS_PROFILE and the credentials file….. but that isn’t happening for me. It panics because the CredentialsProvider is nil.
Bobby R. Ward
Does aws-sdk-go-v2 support credentials through the AWS_ROLE_ARN/AWS_WEB_IDENTITY_TOKEN_FILE env vars? It doesn't look like it but I'm new to go and want to verify.
Kevin Lyda
Hey there. Just a thought, maybe link to the api docs in the README? I'm sure if I was doing Go dev all the time (I wish) I'd be able to quickly type up that godoc url, but I don't so it's hard to remember.
Kevin Lyda
Also, I'm using a NewGetLogEventsPaginator from cloudwatchlogs. I assign it to p and p.Next() always returns true.
The interface type, aws.Pager, says that Next() should return false if there's nothing left. Instead I'm looking to see if len(p.CurrentPage().Events) == 0.
Hello Everyone. I have some questions about the qldbsession service. Hope I can get some advice and help here. Thank you advanced.
Daniel Durante
Does the sdk v2 fix the whole "WriteAtBuffer" memory leak issue?
Vlad Ungureanu
Hey folks, any idea when support for ec2:DescribeInstanceTypes will land in the v2 sdk ?

when initiating an aws session and I've got MFA enabled on my account with MFA serial number in the credentials file I'm getting an error

panic: failed to load config, token provider required for AssumeRole with MFA

when I disable MFA and remove the MFA serial from the credentials, it works. Does this mean MFA is not currently supported?
