  • Can I increment a counter or remove an attribute with an update expression?
  • Does updating a key that doesn't exist yet create the item?

  • Update item {key} in table {table_name} with expression {update_expression}.
  • Change attributes on item {key} in {table_name} only if {condition}, and return the updated values.
