Did you know that there are actually very famous design patterns for converting a monolith to microservices? Do you know of any design patterns?

[Educosys @educosys]

When we start a new system or a project from scratch, it doesn't make sense to get started with a lot of microservices. It just adds a lot of unnecessary complexity. It makes sense get started with a 𝐌𝐨𝐧𝐨𝐥𝐢𝐭𝐡, as needed, we can gradually add 𝐌𝐢𝐜𝐫𝐨𝐬𝐞𝐫𝐯𝐢𝐜𝐞𝐬.

This is exactly what you should do if you have an 𝐋𝐋𝐃 𝐢𝐧𝐭𝐞𝐫𝐯𝐢𝐞𝐰 coming up and you are a beginner! 𝑻𝒉𝒊𝒔 𝒊𝒔 𝒂 𝒕𝒐-𝒕𝒉𝒆-𝒑𝒐𝒊𝒏𝒕 𝒓𝒐𝒂𝒅𝒎𝒂𝒑, 𝒂𝒏𝒅 𝒘𝒆 𝒉𝒐𝒑𝒆 𝒊𝒕 𝒉𝒆𝒍𝒑𝒔 𝒚𝒐𝒖.

Then, it is copied to the user buffer space. When performing a write operation, the data is copied from the user buffer space back to the kernel buffer space, then to the buffer associated with the socket, and finally, it exits the computer.

Zero Copy Transfer is a technique that optimizes data transfer by reducing the number of times data is copied between user and kernel spaces. Initially, data is read from the disks into the kernel buffer space.

With a sorted array, you can perform a binary search, which again would take about 20 milliseconds. However, if we use a B-Tree of order 100, meaning each node can have a maximum of 100 children, it would take only about 3 milliseconds. This is a significant optimization.

Let’s break this down very simply and compare the complexities. If we have a million records in a database, which is a very common use case, let’s compare the time complexity for search operations.

[Educosys @educosys]

Even if each comparison takes 1 millisecond, that would mean a total of 20 milliseconds to search through a million records, which is quite slow. An unbalanced BST or a simple array would take about 1 million milliseconds, which is out of the question.

In C++, learning how to implement multithreading can significantly boost the performance of your applications.

[Educosys @educosys]

Why Learn Multithreading and Socket Programming in C++?

Multithreading is a key technique for making your code run faster and more efficiently by allowing multiple tasks to happen at the same time.

"Mastering Data Structures and Algorithms (DSA) isn't just a challenge;
it's the foundation for every great software engineer. While it may feel like a tough battle, remember that consistency is key. Solving even two DSA problems daily can lead to significant growth over time.
