retry option for data sources

[muang0]

Hi all, I am posting here to gauge interest in a potential feature.

Our use case: We are creating a load balancer via k8s ingress controller, and need to use its a record set in the same module. The record takes time to propagate, which leads to an unresolved error.

I am thinking-- could we add an argument to the data source to retry the dns resolution over a specified period?

--Thanks for the response! 😄

We can use local exec with sleep to wait for specified time.
However that does not guarantee that ALB A record will be available within that time frame.

How to wait and retry until data source is available ??

Could have as another arg, or even -1 value for retry time arg. Just thinking out loud here.

And yes, local exec could work-- but the downside in my mind is that its a less clean solution, and adds reliance outside terraform since local exec would run on the native system.
