Equivalent of -refresh=false at the resource/module level

[dedaimia]

Terraform Version

Terraform v1.2.9
on darwin_amd64

Use Cases

Love the -refresh=false option on terraform plan, as it allows us to skip refresh and significantly speed up plans when we know out of band changes are unlikely (e.g. we just ran another plan and apply a few minutes ago).

However, we also have cases for specific resources where we almost never care about out-of-band changes. It would be nice to skip refresh on these permanently, without having to decide on a run-by-run basis, and without having to also skip refresh on all the other resources in the repo.

Any chance of getting the equivalent of "refresh=false" as a resource meta-argument? Module meta-argument would be great too.

Attempted Solutions

-refresh=false for the entire plan. But then we periodically need to run with -refresh=true or -refresh-only to pick up out of band changes on other resources in the same code

ignore-changes meta-arguent on the resource, but this still spends time checking for, and reports on, out-of-band changes for resources where we do not need to know

Proposal

refresh meta-argument settable to true/false

Thanks for this enhancement request!

So for aws alb the refresh is very slow, it would be nice to have a cache time so we can cache the results for a bit based on the cost of querying them in an adaptive manner.
