Architecting Log-Structured Merge Trees for Write-Intensive Distributed Databases

LSM trees are the backbone of modern write-intensive databases like Cassandra, RocksDB, and ScyllaDB. This post walks through the architecture, compaction strategies, and tuning decisions that separate a healthy LSM deployment from a write stall.
