Atomic commit

Atomic commit is like playing with blocks. When you want to build something with blocks, you have to put them together in a specific order.

Imagine that you're building a tower with blocks, but you don't have all the pieces you need. You ask your friend for help, and your friend gives you a few more pieces.

Now, you have two choices: you can try to put all the blocks together at once, or you can add the new pieces to your tower carefully, one by one.

If you try to put all the blocks together at once, you might drop some of them or build the tower in the wrong way. This is like trying to make a bunch of changes to a computer program all at once. It's hard to keep track of everything, and if something goes wrong, it can be really hard to figure out what caused the problem.

On the other hand, if you add the new pieces to your tower carefully, one by one, you can make sure that everything is working properly as you go. This is like making changes to a computer program one at a time. It's much easier to keep track of what you're doing, and if something goes wrong, you can usually figure out which change caused the problem.

Atomic commit is a way of making changes to a computer program one at a time. When you make a change to the program, it's like adding a block to your tower. You can make sure that each change works properly before you move on to the next one.

And, if there's a problem with one of the changes that you've made, you can "roll back" just that change (like taking a block back off your tower) without affecting the other changes that you've made. This is really helpful when you're working on a big project with lots of people, because it makes it much easier to keep track of what everyone is doing and to fix problems when they come up.
