Add column default value cause table lock
Published: 2023-09-22 07:33:20

# Background
Just sharing the recent DB migration issue.
We are about to add 2 columns in a table, and set default value with NOT NULL.

Original sequelize migration code will be like below.

```typescript
    await queryInterface.addColumn(
      'lines',
      'ad_insertion_type',
      {
        type: Sequelize.DataTypes.STRING,
        allowNull: false,
        defaultValue: 'CSAI',
      },
    );
    await queryInterface.addColumn(
      'lines',
      'product_type',
      {
        type: Sequelize.DataTypes.STRING,
        allowNull: false,
        defaultValue: 'VOD',
      },
    );
```
if translated in raw sql will be like below

```
ALTER TABLE `lines` ADD `ad_insertion_type` VARCHAR(255) NOT NULL DEFAULT 'CSAI';
ALTER TABLE `lines` ADD `product_type` VARCHAR(255) NOT NULL DEFAULT 'VOD';
```

# Concern
What makes us worried is that this change may cause table lock. I checked [mysql doc](https://dev.mysql.com/doc/refman/5.7/en/innodb-online-ddl-operations.html#online-ddl-column-operations) and basically no affect on this `ADD column DEFAULT` clause after online DDL released from version after Mysql5.6.
From the doc we can tell that only column data type change will take lock on the migrated table.

I'm still curious what will happen to our DB migration. So I did some experiments on my laptop.

### data
- insert around 1m rows of data into the tested table

### steps
- run migration with sequelize
- run `SHOW OPEN TABLES WHERE In_use=1;` in TablePlus cli to check if any table been locked
- run random select clause to check if been locked
- run random update clause to check if been locked

The result is not what I expected. It showed that the tested table `lines` had been locked, but none of the query been blocked.
I can only assume that this is row lock instead of table lock.

## followed up
I tried another migration. I changed column row, and update one row with new connection. It's been blocked, which proves that data type change causes lock.

CS50 Web - Project 0

Published: 2023-09-22 07:19:01

Hello!! It has truly been a hot minute since I've written on here but I'm glad to be back. This time around, I'm taking a course called CS50 Web and I want to document my journey through it, especially the projects part. In total, there are 5 projects + a final project to be completed for this course. 

I really like the format of the CS50 series because of the automatic grading system for assignments, but I was pleasantly surprised that not only is this web dev course of CS50 graded automatically, but it is also simultaneously looked over by human graders! In this first project (and probably in the upcoming projects as well), students have to record a screencast of their finished demo and give a verbal explanations with it. I thought this was really nice that they made this mandatory because it could help me with my presentation skills :) 


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/5kbludyc6ppc8do0m71p.png)

This project was to build a clone of Google Search, Google Image Search, and Advanced Search. At first, I thought I had to use some sort of API or build a backend but it turned out that you could just rely on HTML to grab the queries of your inputs. How fascinating! 

For example, to implement the "I'm feeling lucky" button, which takes you directly to the first result of your search, you just have to use this `name="btnI"` thing. 

```html
<input class="input" name="btnI" type="submit" value="I'm Feeling Lucky">
``` 

This project was a good way to make sure you can implement pixel-perfect HTML/CSS by inspecting the original designs using the developer tool. 

Here's my [demo video ](https://youtu.be/aDlDXeaBSGk?si=DuEl78U7Imjd_7RF)with timestamps.
