Is service/dynamodbstreams missing some constants?

[jamessouth]

A bunch of types/constants from service/dynamodbstreams v1 aren't in the v2 godoc and the go tools don't recognize them anymore when you update. They are in a v2 generated file; are they supposed to be accessible to us?

godoc-pkg constants v1 vs v2

Thank you

Hi @jamessouth ,

Are you running into an issue trying to import these constants?

Can you give me your code example? perhaps there's a v2 way of doing things that you might not know about.

Thanks,
Ran

Hello @RanVaknin, yes, since they don't exist in dynamodbstreams v2, I can't import them, so I still use v1. I linked to the constants sections above so you can see they aren't where they used to be. Where were they moved to?

v1:

import "github.com/aws/aws-sdk-go/service/dynamodbstreams"
...
dynamodbstreams.OperationTypeInsert 
// const dynamodbstreams.OperationTypeInsert untyped string = "INSERT" OperationTypeInsert is a OperationType enum value

change to v2, run go mod tidy, now they all error:

import "github.com/aws/aws-sdk-go-v2/service/dynamodbstreams"
...
dynamodbstreams.OperationTypeInsert 
// OperationTypeInsert not declared by package dynamodbstreams

Thank you

@jamessouth Hi, Sorry for the long wait time.

I see this constant under import "github.com/aws/aws-sdk-go-v2/service/dynamodbstreams/enums"
Can you see if this solves your issue?

That's a 404, you mean this. They're available in ...dynamodbstreams/types, so you have to use an import alias since you are also importing ...dynamodb/types. The EventName in the lambda-go stream record is still a string, so you have to cast. Thank you! Happy New Year!

Same to you! 🙏

@jamessouth

Can you please include a complete v2 code example? I would like to know your use case in order to help you.

function, imports, config creation, client creation, API call.

Thank you very much 🙏 ,

Hello @RanVaknin,

My use case is a lambda consumer of DynamoDB stream records. I import the dynamodbstreams package just for these constants, since the aws-lambda-go/events package gives access to the stream records. As I described in my original post, the constants don't seem to exist in v2, so I just use v1. Here is my (~700 lines) file. If you update the import to v2 as I showed in my last post, the 8 uses of the constants turn to errors.

Thank you
