The Unified Compaction Strategy in Cassandra 5

Explore the innovative Unified Compaction Strategy introduced in Cassandra 5 through this informative conference talk. Delve into the challenges of choosing compaction strategies for Cassandra databases and discover how this new approach provides a versatile solution for various use cases. Learn about the strategy's ability to handle leveled, tiered, and time-windowed compaction effectively, while addressing limitations of previous methods. Understand key concepts such as the flexible target state abstraction and SSTable "density," which enable improved concurrency and easier reconfiguration. Gain insights into the seamless upgrade process, as the strategy can work with existing hierarchies. Examine the practical applications of the Unified Compaction Strategy in managing higher node densities and its potential impact on database performance.
