- [ ] support bigtable_app_profile
## Examples
### Simple instance with access configuration
```hcl
module "bigtable-instance" {
source = "./modules/bigtable-instance"
project_id = "my-project"
name = "instance"
cluster_id = "instance"
zone = "europe-west1-b"
tables = {
test1 = null,
test2 = {
split_keys = ["a", "b", "c"]
column_family = null
}
}
iam = {
"roles/bigtable.user" = ["user:viewer@testdomain.com"]
}
}
# tftest:modules=1:resources=4
