Guys, starting my Elasticsearch learning journey today
Will be sharing what I learn, useful notes, and practical insights here.
If you’ve worked with Elasticsearch, feel free to share tips 🙂
Most people study system design like interview theory.
But the real learning starts when you ask questions like:
• What happens when a database goes down?
• How does scaling actually work during traffic spikes?
• Why do some systems choose SQL while others prefer NoSQL?
• How are billions of notifications delivered in real time?
• How do apps avoid single points of failure?
• How does caching reduce server load so massively?
Also, one thing many developers miss:
System design is not just about “designing big apps”. It teaches you how to think like an engineer while building any application.
Even small side projects become 10x better once you start understanding queues, caching, rate limiting, load balancing, indexing, replication, and asynchronous processing.
Your microservices architecture looks clean on paper.
But deployments keep breaking.
Latency keeps increasing.
What usually becomes the real problem first:
Network calls
Observability
Service dependencies
