CockroachDB 25.3 introduces a new feature called "value separation" in its storage layer, which significantly enhances performance by increasing throughput by 50-60% for wide-row, write-heavy workloads. This innovation is achieved through the use of the Pebble storage engine, which organizes data using a Log-structured Merge-tree (LSM). By storing values separately from keys during compaction, value separation reduces write amplification, thereby lowering input/output operations, bandwidth, and storage costs. This allows systems to operate more efficiently, offering higher speed, reliability, and predictability, particularly benefiting data-intensive and write-heavy workloads such as real-time analytics. The feature is currently in public preview and is expected to be generally available in CockroachDB 25.4, where it will be enabled by default. This development not only improves the user experience and application reliability but also reduces the time database teams spend troubleshooting, thus enabling organizations to scale data-intensive workloads without facing costly infrastructure bottlenecks.
