Delete Record in DynamoDB Using Java (Guide w/ Code Examples)

In DynamoDB, the item key and table name are all needed to delete an item. Additionally, it is specifically instructed to use a conditional expression, which will be required to prevent deleting the incorrect items.

public static void deleteDymamoDBItem(DynamoDbClient ddb, String tableName, String key, String keyVal) {
        HashMap<String,AttributeValue> keyToGet = new HashMap<>();
        keyToGet.put(key, AttributeValue.builder()
            .s(keyVal)
            .build());

        DeleteItemRequest deleteReq = DeleteItemRequest.builder()
            .tableName(tableName)
            .key(keyToGet)
            .build();

        try {
            ddb.deleteItem(deleteReq);
        } catch (DynamoDbException e) {
           System.err.println(e.getMessage());
           System.exit(1);
        }
    }
