def conventional_index_name
  # DynamoDB requires index names to be at least 3 characters long, otherwise:
  #   Error: Unable to : 1 validation error detected: Value 'id' at 'globalSecondaryIndexes.1.member.indexName' failed to satisfy constraint: Member must have length greater than or equal to 3
  # The id valid is too short sadly.
  # Adding -index to the end of the index name is a safe way to ensure that.
  # Annoying that the index_name("id-index") is going to be a little longer.
