# Google Cloud BigTable Module

This module allows managing a single BigTable instance, including access configuration and tables.

## TODO

- [ ] support bigtable_gc_policy
- [ ] 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"]
  }
}
