LSM-Tree
This animation is a compact, educational model of a log-structured merge tree backing a simple key-value storage engine. It covers Put, Get, Delete, memtable flushes, and compaction so the moving pieces are easier to reason about. It is not a production-accurate RocksDB, Cassandra, or HBase simulator: bloom filters, block indexes, concurrent background work, write stalls, and real compaction strategies are deliberately left out.
