How can we modify ec2 instance with cdk stack or pipeline?

I am able to launch the ec2 instance but whenever i modify the stack it creates a new instance.

So, any idea how to launch and manage ec2 instances meaning change instance type , size etc programmatically?

Guys, i am having a tough time in work. So, i am sharing the story and questions here-

Initially, i was doing well with new projects and other existing projects where implemented new features.

But recently, i am assigned to a old project created by clients and some senior developer worked on it .

Ps: I was also assigned to this project 8 months earlier but was reassigned to other projects.

Now, Our senior developer who worked on it resigned because of the messy project and a lot of pressure from boss.
my colleague also resigned because of this.

Due to this, all this pressure thrown upon me. I am working on it relentlessly but i am soo burned out that i am actually feeling sick and constantly having headache.

And main thing is that the project has so many errors which iam getting during testing and i have to fix all of the error.
And yes they have documentation but shitty unreadable documentation . My manager also rebuking me why i dont remember things said to me 8 months earlier. (That time i just joined the company)

I don't know what will happen to me if i cant tackle this project.
And what should i do in such cases as my mental health is deteriorating day by day.

Hello, fellow developers, i am having a question in mind that confusing me about my career choices.

At first i joined a company as a full stack developer with 6 months experience in MERN, MySql etc.

Now i have completed nearly 1 year in this company but they are always assigning me to full DevOps CI/ CD projects. And i agree i am learning a lot of new things and completed the given works too.

BUT , the question is , should i completely shift as devops engineer or software developer? What might be a better career in long term?

Ps: in CI/CD i did almost all works in Typescript using CDK and sometimes a little bit in python (not good in python but learning)

is using auto incremented id as primary key bad practice in mysql??

My teacher said it is wrong to use autoincrement because it will skip number when row is deleted. But it does to make it unique .

Or should i use uuid ? But doesn't it impact performance?

Tell me what is value of a "," ( comma) in programming?

Because
I spent a whole day debugging errors one after another and atlast the main reason of all errors leads to a fking comma 😑
