+Recently I came across the problem of how to wipe a dynamodb table.
+I though there would be an ui button for this or at lease an api/sdk method
+but from what I found the only way it to individually delete the items by key. This
+method can be batched up to 10 items per call but is still very slow and incurs write 
+costs.
+
+Since I'm used Terraform to create the table in the first place I thought I'll just destroy it 
+and remake it... Then came the problem of not wanting to destroy everything but simply remake the 
+table. After some digging in Terraform docs I found a pretty clean solution.
+
+
+**main.tf**
+
+```
+module "dynamodb_table" {
+  source   = "terraform-aws-modules/dynamodb-table/aws"
+
+  name     = "poverty-line-county-gps-map"
+  hash_key = "id"
+  stream_enabled = false
+
+  attributes = [
+    {
+      name = "id"
+      type = "S"
+    }
+  ]
+
+  tags = {
+    Terraform   = "true"
+    Project = "poverty_line"
+  }
+}
+```
+
+In this case I wanted to remake "poverty-line-county-gps-map". To find out what
+exactly it is called I ran terraform state:
+
+```shell
+$ terraform state list
+aws_sqs_queue.dead_letter_queue
+aws_sqs_queue.terraform_queue
+module.dynamodb_table.aws_dynamodb_table.this[0]
+```
+
+from here the resource can be remake like:
+
+```shell
+$ terraform apply -replace="module.dynamodb_table.aws_dynamodb_table.this[0]"
+```
+
+Happy times remaking things. 👋
