What is lsm tree. It is designed to A log-structured merge-tree (LSM tree) is a data structure and storage architecture used by RocksDB, the underlying key-value store of DocDB. It is widely used in databases and storage systems, such as Cassandra, RocksDB, and LevelDB. It is optimized for fast writes. LSM trees strike a balance between write and read performance, making them suitable for workloads that involve both frequent writes and efficient reads. May 6, 2023 · LSM tree, short for Log-Structured-Merge Tree, is a clever algorithm design that helps us store massive amounts of data without making us wait forever to write it. The approach is more generally known as the Log Structured Merge Tree, after this 1996 paper, although the algorithm described there differs quite significantly from most real-world implementations. Jun 11, 2025 · A log-structured merge tree, or LSM tree, is a tiered, write-optimized data structure that organizes key-value pairs in multiple components, residing partly in memory and partly on disk. The key idea of LSM-Tree is to first write operations into an in-memory data structure (typically an ordered structure like a skip list or AVL The B-tree and the Log-Structured Merge-tree (LSM-tree) are the two most widely used data structures for data-intensive applications to organize and store data. LSM Trees are the data structure underlying many highly scalable NoSQL distributed key-value type databases such as Amazon's DynamoDB, Cassandra, and ScyllaDB.
