Introduction
Hello!!
I hope you’re doing well. 🫶🏻
In this post, I’ll talk about two different topics, because I didn’t want to write a post with just ONE question. These aren’t common interview questions, but I had to answer them in two separate situations. Since they were so unusual, I didn’t respond as well as I could have.
When should you use it?
- When you want to incorporate changes from a feature branch into the main branch.
- When you don’t need to track individual commits from the feature branch (because all commits will be rewritten and added on top of the target branch).
...
GIT MERGE
Git merge allows you to merge changes from two different branches into one, usually the main branch. In this process, Git creates a new commit to combine the changes.
git merge <branch>
Is noSQL faster than SQL?
In some cases, noSQL can be faster than SQL because it is schema-less and doesn’t need to follow ACID properties. Since there’s no need to validate schemas, data writing and retrieval can be faster. Additionally, noSQL often uses denormalized data, meaning there is less need for JOIN operations, which are among the most performance-heavy operations in SQL.
However, SQL is generally more efficient when working with:
- transactional systems,
- complex queries, and
- situations where strict data consistency and structure are required.
Farewell & Thoughts
I hope these explanations help you in your interviews.
If you have any interview questions you'd like me to answer, or if you want to share your experience, I'd love to hear about it.
See you in the next post!
