The Unified Compaction Strategy in Cassandra 5

compactionLSM treedistributed databaselocal storagemergeApache Foundation

Cassandra, a distributed database built on the Apache Foundation, relies on the LSM (Log-Structured Merge-Tree) architecture to manage data efficiently. At its core, the LSM tree structure enables fast write operations by leveraging local storage and sequential I/O, while read operations require compaction to maintain performance. Over time, the accumulation of SSTables (Sorted String Tables) necessitates a robust compaction strategy to balance read/write amplification. Traditional approaches like Size-Tiered and Leveled Compaction have trade-offs in handling varying workloads. Cassandra 5 introduces the Unified Compaction Strategy (UCS), a novel approach that merges the strengths of existing methods to optimize compaction for diverse use cases.
