A Hotel model (id, name, address, rating). A Booking model (user, hotel, check-in date, check-out date, status). Every time data comes from an API, you need to […]
Idempotency in Rest APIs: Why It Matters
What is Idempotency? Idempotency means that making the same API request multiple times has the same effect as making it once. In other words, no matter how many times you repeat the request, the result and the state of the server remain unchanged after the first successful call. Why is Idempotency Important? Prevents duplicate actions: […]

Why Database Lookups Are Slow—and How Bloom Filters Supercharge Performance
High-scale applications like Twitter, LinkedIn, and Gmail handle millions of users every day. Making sure everything runs smoothly is important, especially for simple tasks like checking if a username is available. But with so many users, even small tasks can slow down the system. This is where Bloom Filters come in. They’re a smart, memory-efficient […]
Understanding Instant Backoff vs Exponential Backoff
When working with systems and networks, temporary failures are inevitable. Services may go down briefly, servers can become overloaded, or network connections may be disrupted. Instead of giving up on the operation, applications usually retry. But how and when to retry makes a huge difference in performance, stability, and reliability. Two widely used retry strategies […]
