Wondering how modern databases like RocksDB, LevelDB, Cassandra, and ScyllaDB achieve lightning-fast writes? In this video, we break down LSM Trees (Log-Structured Merge-Trees) and SSTables (Sorted String Tables) in simple terms—no heavy math required!
🔥 What you’ll learn:
✅ What is an SSTable and how it works
✅ What is an LSM Tree and why it’s perfect for write-heavy workloads
✅ Step-by-step: MemTable → SSTable → Compaction process
✅ LSM Tree vs B-Tree (when to use each)
✅ Real-world examples: RocksDB, LevelDB, Cassandra, BigTable
✅ Pros & cons of LSM-based storage engines
Whether you're preparing for system design interviews, learning backend engineering, or just curious about database internals, this video makes LSM and SST easy to understand in under 10 minutes!
💡 Perfect for: System Design Interviews, Backend Developers, DBA, Computer Science students
