💡 How to Ace System Design Interviews Like a Boss? Follow this 7-step process to do well in a System Design Round 1 - Requirements Clarification In the first step, clarify functional and non-functional requirements. Ask questions to understand the core features of the system as well as non-functional aspects such as data volume, availability, scale, etc. 2 - Capacity Estimation Next, estimate the capacity of the system. Focus on attributes like the number of users, traffic, storage/memory needs, and compute and networking requirements. 3 - Create High-Level Design Break down the system into components such as client apps, servers, load balancers, databases, etc. Start with drawing a simple block diagram that shows these components and their potential interaction with each other. Focus on the data flow. 4 - Database Design Model the data and choose the right database type for the system. Once done, focus on the database schema. 5 - Interface Design Next, focus on the interfaces to the system. This could be API endpoints or event models exchanged between the various components of the system. Also, choose a communication approach such as REST, GraphQL, gRPC, or an event-driven 6 - Scalability and Performance Address the scalability, performance, and latency aspects of the system by suggesting techniques that will be used. For example, vertical and horizontal scaling, caching, indexing, denormalizing, sharding, replication, CDNs, etc. 7 - Reliability and Resiliency Lastly, address the reliability and resiliency of the design. Identify single points of failure and mitigate their impact.

💡 Top 6 Multithreading Design Patterns You Must Know

Multithreading enables a single program or process to execute multiple tasks concurrently. Each task is a thread. Think of threads as lightweight units of execution that share the resources of the process such as memory space.

However, multithreading also introduces complexities like synchronization, communication, and potential race conditions. This is where patterns help. 1 - Producer-Consumer Pattern This pattern involves two types of threads: producers generating data and consumers processing that data. A blocking queue acts as a buffer between the two. 2 - Thread Pool Pattern In this pattern, there is a pool of worker threads that can be reused for executing tasks. Using a pool removes the overhead of creating and destroying threads. Great for executing a large number of short-lived tasks. 3 - Futures and Promises Pattern In this pattern, the promise is an object that holds the eventual results and the future provides a way to access the result. This is great for executing long-running operations concurrently without blocking the main thread. 4 - Monitor Object Pattern Ensures that only one thread can access or modify a shared resource within an object at a time. This helps prevent race conditions. The pattern is required when you need to protect shared data or resources from concurrent access. 5 - Barrier Pattern Synchronizes a group of threads. Each thread executes until it reaches a barrier point in the code and blocks until all threads have reached the same barrier. Ideal for parallel tasks that need to reach a specific stage before starting the next stage. 6 - Read-Write Lock Pattern It allows multiple threads to read from a shared resource but only allows one thread to write to it at a time. Ideal for managing shared resources where reads are more frequent than writes.
