LSM Tree (Log-Structured Merge Tree) Simulator — Interactive System Design Lab

Write records and watch them accumulate in the memtable, flush to SSTables, and compact through levels. Understand why LSM trees offer excellent write throughput and how compaction keeps read performance from degrading.

Understand how write-optimised storage engines like RocksDB work.

This free interactive simulation runs directly in your browser — no account needed. Adjust the parameters and watch how the system responds in real time.
