Hi!!! I have one question about DynamoDb tables. I’m creating a dynamoDB table and passing this TTL configuration:

ttl=aws.dynamodb.TableTtlArgs(
            attribute_name="TimeToExist",
            enabled=False,
        ))

I can create the tablet without any issue but if I redeploy my stack I get and error informing that

ttl

is already defined. Any idea about how can I execute this statement just the first time that I create the table and not the rest of the times that I update the stack?

Add the

ignore_changes

opt?

@little-cartoon-10569 I have tried to ignored the

ttl

property but it doesn’t work. If the

ttl

is disable in every redeploy the stack tries to add the

attribute_name="TimeToExist"

property and if I remove it I got a validation error. On the contrary, if I set ttl True after adding the redeploy doesn’t claim. It seems like the

attribute_name

doesn’t exist on AWS if the

ttl

is disabled but pulumi is always trying to create it. In this moment AWS complains about this because they says that the ttl is already disabled for that table.

Does this problem also apply to the equivalent Terraform code? If this is a problem with an essentially non-declarative pattern being invoked from Pulumi/Terraform, then you might need to remove this code from your Pulumi app and run it in a separate step. AutomationAPi helps with this sort of thing.

I would say that it also happens to Terraform, because finding a solution for the problem I have seen people complaining about it. In fact there is an open issue in terraform to manage it https://github.com/hashicorp/terraform-provider-aws/issues/10304
