1/12/2024 Unified Compaction Strategy (UCS) in Cassandra: Optimizing Data Management with LSM Trees sstablecompactionmemtableApache FoundationLSM tree Cassandra, a distributed NoSQL database, relies on the Log-Structured Merge-Tree (LSM Tree) architecture to manage data efficiently. This design separates write and read operations, with writes initially stored in memory (MemTable) and later flushed to immutable SSTable files. Over time, the accumulation of SSTables necessitates compaction—a process that reorganizes data to maintain performance. Traditional compaction strategies like Size-Tiered Compaction (STC) and Level Compaction (LC) have limitations in balancing read and write amplification. The Unified Compaction Strategy (UCS), introduced in Cassandra 5, addresses these challenges by integrating density-based layering and sharding mechanisms, offering a more adaptive and scalable solution.

1/12/2024 Snapshots for an Object Store: Design, Implementation, and Use Cases snapshotinternal designsobject storeobject questioningApache Foundationuse cases Snapshots have emerged as a critical feature in modern object stores, offering a robust solution for managing data versions and ensuring application consistency. As data volumes grow exponentially, traditional approaches like object questioning—where each modification creates a new version—lead to namespace bloat and manual cleanup challenges. Snapshots, by contrast, provide a declarative way to capture application states at specific points in time, enabling efficient versioning without compromising data integrity. This article explores the design principles, implementation mechanics, and use cases of snapshots in object stores, with a focus on their role in addressing scalability and consistency challenges.
