 * `name` - (Optional, Forces new resource) The name of the log group. If omitted, Terraform will assign a random, unique name.
 * `name_prefix` - (Optional, Forces new resource) Creates a unique name beginning with the specified prefix. Conflicts with `name`.
 * `skip_destroy` - (Optional) Set to true if you do not wish the log group (and any logs it may contain) to be deleted at destroy time, and instead just remove the log group from the Terraform state.
+* `log_group_class` - (Optional) Specified the log class of the log group. Possible values are: `STANDARD` or `INFREQUENT_ACCESS`.
 * `retention_in_days` - (Optional) Specifies the number of days
