title: How to avoid creating existing resources in Terraform?
body: <p>I successfully applied my basic configuration for AWS using Terraform (added a DynamoDB table):</p>
  
  <pre><code>terraform init
  terraform apply -auto-approve
  </code></pre>
  
  <p>After I updated files by adding new resources and ran apply again, I got an error that Dynamo table already exists:</p>
  
  <pre><code>* aws_dynamodb_table.my-table: error creating DynamoDB Table: ResourceInUseException: Table already exists: my-table
  </code></pre>
  
  <p>How can I avoid replacing existing resources?</p>
